Heathrow Airport has revealed details of its plan to expand and modernise the airport at a cost of £49bn.
Thomas Woldbye, CEO of Heathrow Airport, said expansion was "urgent" as the airport was currently working at capacity, "to the detriment of trade and connectivity". The work would be funded by private finance.
The government has backed plans for a third runway, with Chancellor Rachel Reeves saying it would "make Britain the world's best connected place to do business".
However, the plans face opposition from environmental groups, politicians, and locals. London's mayor Sir Sadiq Khan said it would have a "severe impact on noise, air pollution and meeting our climate change targets".
The plans come a day after the deadline set by the government for parties to submit proposals.
