Heathrow Airport says The Project will be financed privately.

more and More people are traveling by plane, than before, and that the left-hand search, the government the possibilities for the expansion of The Airport capacity.

The Cbi , the equivalent of a British company - says a third runway will "set the UK on course for a bright trading future".

The expansion will also benefit passengers, according to The Department for Transport.

Heathrow says, he pays the full market value plus 25% for real-estate in your of expropriation zone, as well as for some of the houses in the area.

The third runway question, Prime Minister Boris Johnson in an awkward Position - especially since his Uxbridge and South Ruislip seat next to Heathrow.

In the year 2015, he said: "I'm going to lie down in front of the bulldozers and the construction of the third runway. "

But, if in the year 2018, Mr Johnson - who was foreign Minister at the Time - missed the vote, as he was traveling to Afghanistan.

Mr. Johnson is not The First watch to fight with the Heathrow expansion issue.

The Labour government first gave the third runway, says green light in 2009, the former Prime Minister , Gordon Brown , it was necessary for economic reasons.

But The Plan was later scrapped by the Conservative-Lib Dem government in 2010. David Cameron , the Prime Minister was, after Mr. Brown had previously excluded, a Heathrow extension "".

The Conservatives 2019 election program says that while the third runway is a private project, Heathrow has to prove, is able to meet its air quality and noise commitments.

Heathrow Airport is the assessment of answers to currently.

The government is also facing a legal challenge. Activists argue that The Proposal is not unlawful, because you take into account the Paris climate agreement to limit global temperature rise to under 2C.

So, depending on the result - there is still no guarantee for the third runway.
