The Labour Leader, Jeremy Corbyn, has told ITV News Tyne Tees that Nissan's investment in the North East must be continued.
Speaking on a visit to the region to mark 80 years since the Jarrow March, he said he wanted to speak to the company to find out exactly what it wants to maintain its investment in the area after Britain leaves the European Union.
Nissan is concerned that tariffs could be placed on British goods, making them more expensive for buyers overseas.
Watch @krisjepson's report here:
The Japanese car manufacture which builds 500,000 cars a year on Wearside wants the UK to pledge compensation for any tax barriers that may be raised as a result of leaving the European Union.
Mr. Corbyn stopped short of promising financial aid but said he did want to make sure Britain negotiates a good working relationship with Europe.
Local Councillor, John McCabe, said Mr Corbyn's approach is wise. He said, "we don't know exactly what's going to happen with tariffs so it's a bit premature for him to give a sensible comment on that decision, because we don't know what the facts are and we don't know what the exit deal is at the moment".
The grandson of the Jarrow March organiser, Peter Tarrack, said Mr Corbyn should not have to negotiate with Nissan over jobs if he becomes Prime Minister.
