There has been confusion on both sides of the House about what the former Secretary of State, my right hon. Friend the Member for Leeds Central (Hilary Benn), who is in his place, did or did not do. He asked the Department for Environment, Food and Rural Affairs to do a thorough search of all the ministerial papers he saw on ash dieback, which has shown that he did not see the correspondence between the Horticultural Trades Association and the Forestry Commission about a possible import ban. The only mention of ash dieback was in a briefing note in February 2010, in which the disease was listed as absent from the country. The hon. Member for Mid Norfolk (George Freeman) chairs the all-party group on life sciences, so he should know that the way the disease has been discovered is still evolving.
In 2009, it was thought that the fungus that caused ash dieback was already present in the UK. It was only subsequently that a new virulent species causing ash dieback was discovered. The science changed in 2010, when a new pathogen, Hymenoscyphus pseudoalbidus, was identified as the fungus causing the disease. I advise all hon. Members to read an article by Andy Coghlan in the New Scientist of 31 October that gives the scientific chronology of the disease. I also have a copy of the scientific paper in Forest Pathology in which the change was first discovered, which was printed in 2011.
What did my right hon. Friend the Member for Leeds Central do? He published the “Forestry Commission: Science and innovation strategy for British forestry 2010-2013” on 1 April 2010. It stated:
“Over the next five years we will increase our budget for monitoring and biosecurity research particularly with regard to tree health to 15% of our research spend.”
Even as late as autumn 2011, the Forestry Commission pathology bulletin confirmed that Britain was clear of the pathogen.

The hon. Member for Bury St Edmunds (Mr Ruffley) made a fair point about the possibility of airborne transmission. Does my hon. Friend the Member for Wakefield (Mary Creagh) agree that there may be connectivity with nurseries to which seedlings were imported? It is quite possible that, over a year, there was airborne transmission to trees, as the hon. Member for Bury St Edmunds suggests, from those imported seedlings. That is not incompatible with his point.
Mary Creagh
It is much more likely that the disease spread from imported seedlings transplanted from nursery stock than that it blew in, on great gusts, over the North sea. We will examine that in more detail later. [Interruption.] Ministers can chunter; the science is not politically convenient for them, but we will stick to what continental scientists have discovered until those facts are disproved.
The disease was discovered in imported saplings in February this year. When did the public first hear that the infection was on UK soil? Was it in April, when Ministers were told that it had been discovered in a nursery? No. Was it in June, when it was discovered in newly planted sites, and there was increased risk to mature woodland, as the disease could blow in from those sites? No, it was not. We finally heard on 25 October, when the Secretary of State announced that he would ban ash imports during Department for Environment, Food and Rural Affairs questions in the House—a full eight months after the disease first appeared.
Ministers could have started the consultation on a ban back in April, instead of leaving it until the end of August. The question on everyone’s lips is: “Why didn’t they?” The Secretary of State told the House on 25 October:
“The minute we heard about this, we launched a consultation.”—[Official Report, 25 October 2012; Vol. 551, c. 1066.]
Does he understand that a consultation is not a ban? Why did Ministers keep the public in the dark? This really matters, because scientists have lost eight months in our fight against ash dieback, as the diseased leaves have already fallen. I congratulate the university of East Anglia on its ashtag.org app and website, but what a shame it did not know that there was a problem in April, when Ministers did. Ministers’ incompetence has meant that we are behind the curve of the disease’s spread. This matters because we, the public, who love our forests, may have unwittingly spread the disease from June to October, the main fruiting season for the fungus. Had we known in spring, we could have completed a comprehensive survey this summer, using public good will. Ministers’ incompetence has helped the disease spread and will cost the taxpayer money.
Mary Creagh
As a scientist, does the hon. Lady understand epidemiology? The dots are all different colours: the red ones represent mature woodlands, and there are others for trees planted out in newly planted sites and nursery sites. The ones in the south-west are in nursery sites: there are no red dots in the south-west, ergo the disease seems to have spread from—[Interruption.] My theory, and it has yet to be disproved—[Interruption.] No, I shall come on to that, but I wish to make progress. I shall explain it to the hon. Lady.
Mary Creagh
No, I shall make progress.
We had a 15-minute briefing from the Secretary of State last Wednesday, for which I am grateful, and we discussed the spread of the disease with Ian Boyd, DEFRA’s chief scientist. A document containing 10 key scientific facts was produced last Wednesday. Bullet point 10 said:
“Wind-blown spores may be dispersed up to 20-30 kilometres, (high confidence)”.
I was therefore surprised at the briefing to hear that the infection had blown in on the wind across the channel and the North sea, even though the channel is 30 km wide at its narrowest point. I was even more surprised, as the week went on, to learn that it had blown hundreds of miles across the North sea to infect mature trees in Northumberland and Scotland.
The key scientific facts document is quite clear:
“Longer distance spread occurs via infected plants or potentially via wood products”.
That would explain the infection in the south-west that the hon. Member for Totnes (Dr Wollaston) is worried about. However, it is politically inconvenient to have a disease which Ministers knew was in the country, with saplings left to infect their wild and mature cousins. I grew suspicious when I realised that the Forestry Commission's key scientific facts, published on Wednesday, changed over the weekend. Bullet point 10 now says:
“Wind-blown spores cause the disease to spread up to 20-30 km per year”.
The inconvenient fact that the wind blows the spores just 20 to 30 km has completely disappeared. A whole new fact, however, has emerged:
“On occasions, spores may disperse much further on the wind.”
However, unlike every other key scientific fact that is categorised as low, medium or high confidence, there is no scientific reference to back up this new scientific fact, because there is none. As yet, I have not seen any evidence to back up Ministers’ claims about the wind. The disease has moved slowly and predictably across Europe, yet now it has developed new powers to cross great seas on the wind.
Is an alternative scientific theory possible? Is it not possible that ash dieback has spread to mature trees in Northumberland and Scotland from the infected saplings that were planted out last winter and on which the fungus fruited this summer? It is certainly possible, and I would argue more probable than those gusts of wind.

I entirely endorse my hon. Friend’s remarks. The only thing that I find more smug than the comments that have been made was the fact that, during the entirety of oral questions to the Deputy Prime Minister, he refused to answer any of the questions that he would have found difficult to answer. One wonders why they are called oral questions to the Deputy Prime Minister if he is not going to bother to answer them.
Mary Creagh (Wakefield) (Lab)
How does my hon. Friend feel that the Budget will impact on the poorest of his constituents in Brent? The impact will be felt by the poorest people across the country, but does he agree that, with this Budget, we have finally seen the Liberal Democrats for what they are: the real wolves in sheep’s clothing?
Barry Gardiner
My hon. Friend is absolutely right. It is very clear that the Liberal Democrats vary not just what they say from doorstep to doorstep, but what they say before the election from what they do after the election, and many of us have bitter experience of that.
Today, it was interesting to hear the Chancellor say that council taxes will be frozen. I thought to myself, “Yes, I’ve heard that mantra before.” My hon. Friend prompts me. That is exactly what the Liberal Democrats promised in the run-up to the 2006 local elections in Brent. Strangely, after that local election, they went into a coalition with the Conservatives, who had promised not just a freeze on council tax but a reduction in council tax. When they got into power, what did they do? They raised council tax for three years in a row.
Moreover, before the election, the Minister of State, Department for Education, the hon. Member for Brent Central (Sarah Teather), was photographed with the elderly—I have a copy of it here—and appeared on a leaflet that said, “Free Personal Care for the elderly say Lib Dems”, but when they got into office on Brent council, they raised the personal care charges from £5 an hour to £16.50 an hour.
When the Chancellor talked today about how the Government would freeze council tax, I thought, “Yes, I know how they will manage to do that.” All the charges that councils make people, such as elderly residents in Brent, pay will be bumped up. The increase will be imposed not on council tax, but on those who have the very least ability to pay—the most vulnerable people in our community.
Last week, I was invited to the Brent Teachers Association meeting to debate the future of education in the borough with the Minister of State, Department for Education, the hon. Member for Brent Central. As she had promised in her election literature an extra £2.5 billion towards education and smaller class sizes, but subsequently approved a £1.88 million cut to the borough’s education area-based grant, I was looking forward to that debate. However, I understand that, half an hour before the start of it, her office phoned to indicate that she was indisposed and could not attend. If I had been in her position, I would have been indisposed and unable to attend, too. To cut one’s education department in the borough, having promised such a vast increase in the education spending, is typical of how the Liberal Democrats have proceeded around the country, and we now see that what they do in national government is absolutely no different. The disillusion of those who believed the Liberal Democrat promises before the election can be only further deepened by the Budget statement that they have heard today.
