>> We've heard it all before. But this time apparently it's for real. A decision on where to allow airport expansion near London will be made on Tuesday. More than 40 years after it was first put on the table. Reuters correspondent Sarah Young has been following recent developments.>> Should this decision be made and then that runway be built.
It will be the first time since the 1940s that a new full-length runway has been built in the Southeast of England. So it's potentially a really kinda historic day.>> Historic but also hugely controversial. Heathrow is already Europe's busiest airport. Residents and environmental groups fear a third runway will mean more noise and air pollution.
Another runway at Gatwick would be considerably cheaper and there's more space there but last year an independent inquiry said that Heathrow makes more sense. It's thought the government is about to agree.>> What's kinda hinting at that is cabinet ministers will be able to voice their opposition to the government.
That's quite unusual, and it suggests that the decisions that is going to made is controversial>> Borris Johnson is among those who oppose Heathrow expansion along with education secretary Justine Greening, potentially making it a close call when the decision goes to parliament.>> We actually think that the vote will go ahead in favor of Heathrow.
Because lots of oppositions MP's, labor MP's support it. As do lots of MP's who aren't necessarily based in the region that's gonna be affected by the noise pollution.>> The spades in the ground are still a long way away. A public consultation is the first hurdle, while legal challenges have been promised whatever the decision.
