The opportunity to end decades of political dithering on airport expansion has been squandered, the UK transport committee has argued in a report on airport expansion in the south-east of England.In the report, the committee urges the secretary of state to set out a clear timetable for expansion, making clear the measures which have been accepted or rejected and the work which needs to be completed.

The report concludes that arguments for and against expansion have changed little in a quarter of a century.The committee continues to back Heathrow, with the package of accompanying measures recommended by the Airports Commission. However, the Conservative government has refused to take a decision on the issue until after the London mayoral election, further delaying the process.
