I beg to move,
That this House has considered the matter of transportation of nuclear warheads.
I thank the Minister for being here, and I hope that she can answer some of my questions about the transportation of nuclear warheads. It may come as a shock to many, but nuclear weapons are regularly driven past the homes of millions of people as they snake their way across Britain. Nuclear warheads were transported through my constituency at least three times in the last 18 months: in January and July 2014, and in January 2015. They were moved in large convoys of more than 20 vehicles on the M74 through Rutherglen and across the centre of the city of Glasgow.
On each occasion, they were travelling around midnight. Driving in the dark involves particular risks; the Royal Society for the Prevention of Accidents has pointed out that drivers are far more likely to fall asleep at the wheel at night. Although only a quarter of all journeys take place between 7 pm and 8 am, 40% of all injuries sustained in accidents occur during this time period.
For several years, the convoys avoided the centre of Glasgow and skirted around the city. Now that restriction has been lifted, and they travel openly on the M74 and M8 through the heart of Scotland’s largest city. Until 2005, nuclear convoys took their time on the long journey from Berkshire to Coulport. Each trip took three days, with two overnight stops. Now the convoys’ journey is continuous, with a crew change halfway and no overnight stops. That means longer stretches on the road, driving at night, driving through urban areas and driving for longer, which all make the dangers of an accident even greater than in the past.
I am aware that the Ministry of Defence will be able to cite numerous safety procedures that are adhered to. I am also aware that the MOD carries out regular safety exercises and will consider its emergency plans to be robustly tested. But accidents can and do happen. In January 1987, in the county of Wiltshire, two nuclear warhead carriers, each transporting two nuclear warheads, came off the road after sliding on ice. One of the carriers suffered damage after rolling on its side. Fortunately, the containerised weapons were not damaged in the incident, but it took 18 hours to recover the damaged vehicle.
The MOD has failed to learn lessons from that accident. It continues to move nuclear weapons in the middle of winter, in icy conditions. At 11 pm on 11 January this year, a convoy drove past a sign on the M74 at Hamilton that said “Winter weather, take care”. It then went through my constituency, across Glasgow and over the Erskine bridge, 45 metres above the River Clyde.
Does my hon. Friend agree that there is no better example of the MOD’s blatant disregard for public safety in transporting nuclear warheads than when that convoy crossed the Erskine bridge in my constituency? The Erskine bridge, high above the Clyde, had been subjected to gusts of nearly 100 mph, and high-sided vehicles had been advised not to use the bridge. I cannot imagine a more ridiculous decision, made solely for convenience rather than safety. It is a completely wrong-headed approach to dealing with such a cargo.
I concur with my hon. Friend. The convoy proceeded despite the high wind warnings flashing on approaches to the bridge. For several days the Met Office had been issuing warnings across the country of high winds or snow. It would not have been possible for the convoy to complete its journey that week without driving at some point through an area where there had been an extreme weather warning.
In addition to the accident in Wiltshire, there have been other accidents: warhead transporters have crashed into each other, a nuclear lorry has been involved in a fatal head-on collision and a convoy has been stranded for hours following a major breakdown. In August 2014, the Sunday Herald newspaper reported that more than 70 safety lapses had occurred on nuclear convoys in the five-and-a-half-year period ending in December 2012. Like many others, I was shocked to learn that such safety incidents have occurred more than once a month on average. In 2012 alone, 23 incidents happened, raising fears that the safety of nuclear convoys might be deteriorating.
In 2005, the same newspaper also revealed an internal MOD report warning that nuclear warheads could accidentally explode if involved in a major crash, because a bomb’s key safety feature could be disabled, leading to what the MOD terms an “inadvertent yield”. That is a rather abstract way of saying that a burst of incredibly lethal radiation would be unleashed. The consequences of an accident could be catastrophic. If there were a major fire or explosion, lethal plutonium would be scattered downwind. Plutonium-241 has a half-life of 24,000 years and is difficult to detect. An accident in my constituency could leave it and neighbouring constituencies a wasteland.
Now it looks as if more convoys than ever will be travelling to and from Scotland. The MOD has a plan to overhaul and upgrade the entire stockpile of Trident nuclear warheads, the Mk4A refurbishment project. Successive Ministers have been coy about telling Parliament about those upgrades. Surely taking all the warheads down to Berkshire and then back to Scotland will mean that we can look forward to an increase in the frequency and size of convoys over the next few years.
