Labour MP George Grogan has claimed plans to extend Heathrow airport could be shelved, the Press Association has reported, which could affect offices in London.
He said that senior ministers are turning against the development of a third runway and have encouraged him to table an Early Day Motion in the House of Commons.
If given the go-ahead, the expansion plan could have a major impact on London offices and businesses across the country.
International firms are likely to welcome any moves designed to speed up transit to their offices in London.
“I have spoken to senior ministers about this and their minds are very much focused on the economy at the moment,” Mr Grogan said.
Proposals to expand the airport have provoked strong opposition from environmental and interest groups.
According to the Press Association, Mr Grogan said the government also needed to consider its popularity in nearby marginal seats and noted there were also “wider environmental questions” to be considered.
The No Third Runway Action Group has claimed that it makes no sense to build a third runway “in an area already struggling with high levels of noise and pollution”.
