Air Traffic Control Disruption

Nusrat Ghani Excerpts

Thursday 10th September 2026 Commons Chamber

[Madam Deputy Speaker (Ms Nusrat Ghani)]

Before we come to the urgent question, I must say how disappointing it is that the Government were not forthcoming with a proactive ministerial statement on this matter. The disruption to aviation and the impact on many constituents has been considerable. I hope the Minister and the Treasury Front Bench will pass that message on to the Secretary of State.

I thank the shadow Minister for his questions. He asks me for more detail about what exactly happened, given that a cyber-attack has now been ruled out. The disruption was caused by a technical issue in NATS’s Swanwick flight processing system, which affected the processing of flight plans used by data controllers. NATS advises that the problem was affecting the flight processing system and the data that was being fed into controller radar displays. A fix was implemented later in the day, but recovery took time, as NATS needed to test that the system was safe.

The shadow Minister is right to raise the experience of Martin and the other hundreds of thousands of passengers across the United Kingdom who were adversely affected. That raises serious questions about contingency and resilience planning at our airports, and I am determined to have conversations about that with the CAA, NATS, airlines and airports in the coming days.

The shadow Minister criticises the fact that it will take around a week to get the report back. It is incredibly important that we take the time to figure out exactly what happened, because ultimately this is about aviation safety. It is about making sure that the UK can retain its reputation for getting passengers to where they need to go while protecting their safety. He asked about the report coming back over recess; I am happy to return after recess to answer any questions that hon. Members may have about the issue.

There is a broader question about the CAA being asked to conduct an urgent review and report back within six months, and whether that is the right timeline. I remind hon. Members that after the largest recent outage, in 2023, it took two and a half years for the CAA to fully assess the implications and all the technical improvements and requirements that were needed as a result of that incident. It provided 34 recommendations, all of which have been implemented. A six-month timeframe to get to the bottom of what is a highly technical matter and an incident of disruption is proportionate and timely, and will allow us to react quickly, with stringent ministerial oversight.

The shadow Minister asks Ministers to take control of the situation and exercise effective oversight on behalf of passengers—that is exactly what we are doing.

[Madam Deputy Speaker (Ms Nusrat Ghani)]

I have noted the Minister’s proactive commitment to a ministerial statement.

[John McDonnell (Hayes and Harlington) (Lab)]

I thank the Minister for his statement. NATS used to be in my constituency and then moved down to Swanwick. Of course, with Heathrow in my constituency, I receive—as I mentioned yesterday—a large amount of correspondence from a whole range of other MPs’ constituents, who think I am responsible for Heathrow airport.

[John McDonnell]

Can you control these people, Madam Deputy Speaker?

[Madam Deputy Speaker]

Order. Mr Gemmell!

[Alan Gemmell (Central Ayrshire) (Lab)]

It was behind me.

[Madam Deputy Speaker]

Well, that was very well done, then.

[John McDonnell]

It is not a laughing matter—I am sorry for interrupting the flow of the discussion.

It would be useful if the review looked at NATS’s long-term investment plans, particularly since its partial privatisation in 2001, which I opposed.

I thank the Minister for meeting Unite this morning and thanking the workers, who have worked so hard. From my experience, when things go wrong at NATS, the Public and Commercial Services Union members—the technical members—scramble and work incredibly hard to put them right. I hope that we can thank them as well. The Opposition spokesperson never made any reference to the workers themselves. They have worked incredibly hard and, as the Minister said, some of them have experienced horrendous abuse. We should congratulate them and support them in their work.

I thank my right hon. Friend for his constructive question. He is right to ask whether NATS’s resourcing is exactly where it needs to be to ensure that we have the capacity and the right people in the right places to deal with these issues when they arise. I am confident that the fantastic teams of people working at NATS responded with all possible haste and diligence to the disruption that was experienced, and I thank them for doing so.

My right hon. Friend raises broader questions about NATS’s resilience. Part of that is about implementing the large-scale technological transformation programmes that are required to ensure that our air traffic control systems are fit for purpose. More often than not, the UK has a formidable reputation for aviation safety, but that does not mean that when disruption like this occurs, we should not take a cold, hard look at NATS’s processes and see where we can do better.

[Madam Deputy Speaker (Ms Nusrat Ghani)]

I call the Liberal Democrat spokesperson.

[Olly Glover (Didcot and Wantage) (LD)]

I thank the Speaker’s Office for granting this urgent question. I join the Minister and the right hon. Member for Hayes and Harlington (John McDonnell) in thanking airport, airline and air traffic control staff for handling this incident and helping passengers who experienced such significant disruption.

This is the third major incident in recent years to do with our air traffic control systems. Given the poor passenger experiences, the poor management of the disruption and the poor customer service resulting from it, should the Government not commit to fixing our air traffic control systems before they commit so enthusiastically to massive aviation expansion, which our current systems and processes may not be able to accommodate?

[Keir Mather]

I thank my hon. Friend for his determined advocacy for passengers with disabilities in both our aviation sector and the wider UK transport system. He is right that the Bill will enable the Secretary of State to conduct a review of how to enhance air passenger rights, particularly for those who can face the most acute forms of disruption while travelling, including people with disabilities or other protected characteristics. We need to take a cold, hard look at how some of the most vulnerable people in society are affected by disruption of this nature, and think about how we can strengthen our air passenger rights regime to respond effectively.

[Madam Deputy Speaker (Ms Nusrat Ghani)]

Order. Do you need medical assistance, Sir Alec?

[Sir Alec Shelbrooke (Wetherby and Easingwold) (Con)]

I am okay, Madam Deputy Speaker. I will struggle on, thank you very much.

The Minister has outlined that there is an investment programme for technology and upgrades, but with software upgrades, there is always the concern that the premise of the programmes will keep getting changed, and that can bring in delays or bugs to a system. Does the Minister have oversight to ensure that the plans for what needs to be done do not keep getting sidetracked by people deciding, “This is a bit more shiny—we should do that”? That would delay the whole thing, and leave us with what looks like an increasingly antiquated system.
