Car giant Nissan warns its Sunderland plant could shut without an EU trade deal.
The firm’s chief operating officer Ashwani Gupta said: “If we are not getting the current tariffs the business will not be sustainable.”
Nissan had said the plant, which employs 7,000, remains “important” to its plans after announcing its facility in Barcelona would close.
Boris Johnson has been adamant he will not seek to extend the Brexit transition, which ends on December 31, despite fears an EU trade deal won’t be concluded by then.
Washington and Sunderland West Labour MP Sharon Hodgson said: “The Government must not risk the livelihoods of thousands who rely on the plant in my constituency by pursuing a reckless no-deal.”
Automative analyst David Leggett, of GlobalData, warned: “Considerable uncertainties remain in terms of future capacity and employment. Nissan wants to avoid new tariffs.”
Mr Johnson is taking “personal charge” of desperate efforts to prevent a new Brexit no-deal nightmare.
Ministers fear Britain is locked in a “death grip” with Brussels which threatens the end-of-year deadline for an exit agreement.
No-deal fears are growing amid a row over fishing rights and delays to talks caused by coronavirus.
And the PM has upped the stakes by letting it be known he is prepared to walk away if he does not get a breakthrough in virtual meetings with other leaders in the next few weeks.
The stand-off is seen by Tory MPs as a major reason why he fought so hard to keep his lockdown-busting Brexit guru Dominic Cummings.
The Government has until the end of June to say whether or not it wants to extend the December 31 deadline.
