Pirelli has temporarily halted work at its UK factories of Burton on Trent and Carlisle from 23 March, with no visitors allowed on either site.

Supply to clients, however, will continue by drawing on the available stock.

“Pirelli will closely monitor the situation surrounding Covid-19 and its impact on the market to establish when production at the plants can recommence,” said a Pirelli statement.

“Pirelli, giving priority to the health of its employees, is constantly monitoring the evolution of the situation and is ready to restart operations at the earliest opportunity.

“Smart working and social distancing measures are already in place with Pirelli employees and commercial, logistic and other customer facing functions continue to serve our clients whilst practising the measures advised by the government and Chief Medical Officer.”
