The Unite union called on the Prime Minister, London Mayor Boris Johnson and other top Tories today to save the maker of black cabs and ensure the iconic vehicle is built in Britain.
This week a decision over the future of Coventry manufacturer London Taxi International (LTI) enters its final stages.
Its administrator Price Waterhouse Cooper, which is managing the sale of the company's assets, could make a decision on LTI's future by the end of the month.
Unite assistant general secretary Tony Burke, who is campaigning to save the maker of the iconic vehicle, said: "The black cab is part of Britain's manufacturing heritage and part of our national fabric, like Big Ben or fish and chips, but now they could disappear from our roads."
LTI went into administration in October and sacked 156 workers, suggesting that the company could collapse or the black cab could end up being built abroad.
Mr Burke said: "It is unthinkable that the historic black cab could be built anywhere else but in the UK. Unite, which represents the workers at London Taxi International and London black cab drivers, is campaigning to save the black cab and continue to have them built in the UK.
"Unite is asking you to commit your personal support to our campaign to ensure that the iconic black cab continues to be built in the UK."
Foreign Minister Alistair Burt's admission that the Cameron government has "supported" a survey of attitudes to US drone strikes in Pakistan's tribal areas amounts to a tacit admission of British involvement.
