The government has "moved heaven and earth" to accelerate Heathrow's third runway, Transport Secretary Heidi Alexander said, in the most supportive ministerial comments on the £49bn megaproject since the expansion's political future was thrown into doubt.

Alexander told an aviation summit that no government "has moved further and faster on airport" improvement than the current Labour administration. She pointed to its approval of Gatwick and Luton expansions as a "shot in the arm" for the South East, before extending the argument to Britain's biggest hub.

"We've been clear that a third runway has the potential to unlock opportunities, jobs, investment and growth across the country," Alexander said. "That's why we've moved heaven and earth to deliver a draft Heathrow [planning blueprint] faster than anyone expected."

Why the comments matter

The remarks carry weight because of what came before them. Prime Minister Andy Burnham, speaking in the days before September's Labour party conference, branded the runway decision "a matter for London and Londoners" — a striking departure from the Starmer government's line, which had made the megaproject a key pillar of its growth agenda.

Burnham has refused to back the £49bn scheme since entering office. Alexander's speech now pulls the government's posture back toward support, without resolving the tension at the top of the administration. That tension is the mechanism to watch.

What happens next?

The process runs through planning law, and the next step is already on the calendar. Earlier this year the government closed a public consultation on the planning framework against which ministers will judge applications from both Heathrow airport and rival bidder Heathrow West.

The final draft — known as the National Policy Statement (the formal planning blueprint MPs must approve before projects can proceed) — is expected to be published early next year, ahead of a crucial vote in the Commons.

That vote is the real decision point. It will determine whether Heathrow, or Heathrow West, or neither, gets a pathway to build. Everything Alexander said at the summit is, in effect, pre-positioning ahead of it.

The government's claim to speed rests on one verifiable fact: the draft Heathrow planning blueprint has arrived faster than observers anticipated. Ministers want that record of delivery noticed before MPs are asked to sign off.

Air traffic control outages draw ministerial anger

Alexander did not confine herself to expansion. She also launched a fresh broadside at the organisation responsible for Britain's air traffic control system, which has suffered two major outages this year.

The breakdowns left thousands of passengers stranded and triggered a wave of cancellations and delays. The transport secretary said she was "angry" at what happened.

"The impact on passengers was simply unacceptable, and it would have been even worse had the airlines and airports not pulled out all the stops to clear the disruption in just a few days," she told the Airlines 2026 conference.

A watchdog inquiry into the failures is due to publish its results soon. Alexander gave a blunt commitment on follow-through.

"I can assure you that I will do whatever it takes to ensure that lessons are learned," she said.

The stakes for business

For executives watching from the sidelines, the speech sends two signals. First, the cabinet member responsible for transport is now publicly and explicitly aligned with Heathrow expansion, framing it as a national growth project rather than a London concern — a direct rebuke to the framing that cast the decision as purely local. Second, the legislative machinery is moving: consultation done, National Policy Statement expected early next year, Commons vote to follow.

The unresolved variable is the Prime Minister. Until Burnham either endorses the £49bn scheme or stays silent through the vote, the government's position remains a transport secretary campaigning hard while the occupant of No 10 holds the final word.
