RAIL union RMT has ridiculed a crackpot Tory scheme to make London’s transport workers take the temperatures of more than a million passengers to help control the spread of Covid-19.

Nickie Aiken, the Tory MP for the Cities of London and Westminster, suggested that transport workers should be conducting checks on commuters travelling into the capital’s hubs.

According to Transport for London some 650,000 passengers used London’s Tube network and 760,000 took bus journeys on Thursday, with passenger numbers increasing rapidly as the government continues to pressure workers back into workplaces whatever the risks.
