The Labour Government has chosen £33billion plan for Heathrow Airport's third runway, selecting it over a competing scheme put forward by hospitality entrepreneur Surinder Arora.
Transport secretary Heidi Alexander confirmed the decision in a statement to parliament, describing Heathrow’s proposal as "the most credible and deliverable option" for expanding Britain’s busiest airport.
The Arora Group’s design centred on a shorter 2800 metre runway intended to avoid diverting the M25.
Ministers concluded the plan would still significantly affect the motorway while requiring the compulsory purchase of additional homes near the airport.
Ms Alexander said the Government intended to move the project forward rapidly.
She stated: "We're acting swiftly and decisively to get this project off the ground so we can realise its transformational potential for passengers, businesses and our economy sooner."
The announcement represents a major development in the long-running debate over airport expansion in the southeast. The project must still progress through detailed planning stages before any construction begins.
Heathrow’s selected blueprint includes a 3500 metre runway and a major reconfiguration of the M25. The plan involves building a new tunnel and bridges around 130 metres west of the existing road.

Modifications to the motorway are expected to cost £1.5billion and form part of the overall £33billion runway budget. A further £15billion will be used for wider airport improvements.
The expansion would significantly increase Heathrow’s operational capacity. It is expected to handle seven hundred and 56,000 flights each year and accommodate 150 million passengers annually.
Achieving this scale would require the demolition of some nearby communities to make space for new infrastructure. Funding for the runway will be provided entirely through private investment.
Heathrow has committed that taxpayers will not contribute to the construction of the runway or associated transport works. Increased airline charges are expected to support the financing model.

The airport has argued the expansion will enhance connectivity, support international trade and generate substantial economic opportunities for British companies involved in design and engineering work.
The Department for Transport said choosing Heathrow’s proposal does not represent final approval for the runway itself.
Officials said the exact runway length and infrastructure requirements will be examined further during the planning process. Ministers aim to reach a planning decision by 2029.
If approval is granted, construction could start in time for the runway to become operational in 2035.
Ms Alexander outlined the next steps, saying: "Today is another important step to enable a third runway... setting the direction for the remainder of our work to get the policy framework in place for airport expansion.
This will allow a decision on a third runway plan this parliament which meets our key tests including on the environment and economic growth."
The transport secretary said the Government would work with the Climate Change Committee to ensure any expansion aligns with the United Kingdom’s carbon reduction commitments.
Heathrow-commissioned research suggests more than one hundred thousand jobs could be created if the runway proceeds.
Heathrow welcomed the Government’s decision while asking for greater regulatory clarity.
A spokesperson said expansion would deliver "more connectivity, increased trade, improved passenger experience and a huge economic boost for the British businesses that will help design and build it."

The airport operator has called for "definitive decisions" from both the Government and the Civil Aviation Authority by mid-December to enable work on the next phase of planning.
Hotel tycoon Surinder Arora, said his group "accepts today's announcement", despite losing the design competition.
He said the company remained interested in acting as the runway’s promoter and argued that competition was "absolutely imperative to keep costs under control at the airport."
The project will now undergo further consultation as ministers update the Airports National Policy Statement, which guides aviation planning decisions.
Parliamentary scrutiny and public engagement will shape the final design before any construction can proceed towards the proposed 2035 opening date.
