Gatwick has said its expansion plans are cheaper and far more beneficial than Heathrow's.

Heathrow and Gatwick airports have both unveiled revised expansion plans to the Airports Commission in a bid to secure permission to build a new runway.

The west Sussex airport said expansion at Gatwick would deliver the following benefits:

• Will achieve £40 billion more in economic benefits to the UK than expansion at Heathrow
• Expansion will deliver more than 120,000 jobs in London and south east England
• Fewer people will be affected by noise pollution

• Around 10 million more passengers would be able to travel with a second runway at Gatwick each year than with a third runway at Heathrow

The Airports Commission is considering the following expansion plans:

• Heathrow
• Gatwick
• Heathrow Hub
• Thames Estuary

Heathrow's bosses are set to lay out revised plans for the airport's proposed expansion which includes an improved compensation plan for those affected by the building of a third runway.

Bosses will allocate £550 million for noise insulation and property compensation to local people.

Around 750 homes would need to be compulsorily purchased to provide space for the extra runway at the west London airport.

The proposals, which will be submitted to a Whitehall-appointed Airports Commission, will propose compensation of 25% above market value plus stamp duty costs and all legal fees, in relation to purchasing a new home.

The plans also include making those dropping off passengers at Heathrow by car being subject to the congestion charge - once transport improvements are finished.

Heathrow and Gatwick will submit their final proposals in the battle over expansion rights today.

They will publish their plans to the Airports Commission, an inquiry led by former Financial Services Authority chairman, Sir Howard Davies.

A decision will then be made into where the next runway in the south east of England should be built.
