LONDON (Reuters) - Talks between the British government and Nissan <7201.T> are ongoing over a future investment from the Japanese carmaker into its plant in Sunderland, northeast England, a spokesman for Prime Minister Theresa May said on Friday.

Nissan will decide next month whether to produce its new Qashqai SUV at its British plant or elsewhere in the first major investment decision affecting Britain's auto sector since Brexit, Chief Executive Carlos Ghosn said on Friday.

"As you saw relatively recently the prime minister had a very productive conversation with the president of Nissan and obviously the dialogue between government and Nissan is ongoing," May's spokesman told reporters.
