Nissan's views on Brexit and how it may affect its operations in Sunderland have fluctuated since the vote to leave the EU.
Here we look at some of the key quotes for Nissan bosses and others on how Brexit could impact on its future investment in Wearside:
"Our preference as a business is, of course, that the UK stays within Europe – it makes the most sense for jobs, trade and costs. For us, a position of stability is more positive than a collection of unknowns."
Nissan chairman and chief executive Carlos Ghosn, February 2016
"We will not be commenting at this time."
Nissan spokesman the morning after the Brexit vote, June 24 2016
"The support and assurances of the UK government enabled us to decide that the next-generation Qashqai and X-Trail will be produced at Sunderland."
Carlos Ghosn, October 2016
"When the package comes, you are going to have to re-evaluate the situation, and say, `Okay, is the competitiveness of your plant preserved or not?'
"We are going to have to make decisions on investment within the next two to three years, so obviously the faster the Brexit results come, the better it is"
Nissan chief executive Carlos Ghosn, January 2017
"At the moment we have got a set of circumstances we are happy with and we will honour that decision going forward. But if anything materially changes, we would review constantly."
Nissan senior vice-president Colin Lawther, February 2017
“We will continue to work with the British Government to ensure the company’s long-term success and investment in the UK.”
Nissan spokesman, August 2017
“If there is no profitability of continuing operation in (the) UK, not Japanese only, no private company can continue operations. (It's) as simple as that. High stakes that I think all of us need to keep in mind.”
Japanese ambassador Koji Tsuruoka, February 2018
"The current position, with conflicting messages and red lines, goes directly against the interests of the UK automotive sector which has thrived on single market and customs union membership."
Mike Hawes, chief executive of The Society of Motor Manufacturers and Traders (SMMT), June 26 2018
"Obviously for us the stakes are very high, but it's difficult to tell you what kind of decision we're going to take without knowing exactly what is Brexit."
