Nissan's decision to manufacture a new model at its Sunderland plant is "a huge vote of confidence" in the UK, according to the Vice-President of UK Manufacturing Kevin Fitzpatrick.
He told the BBC: "This will put the plant under 24-hour running so it is a big boost."
He did not reveal any details about the new model except that it would be a "c-type hatchback" and would aim to compete with cars like the Ford Focus.
David Cameron said: "It is fantastic news that Nissan will be building their new hatchback model in the UK and that they expect to create more than 1,000 jobs at the Sunderland plant and in the supply chain across the country.
"It's proof of the strength and vitality of the British manufacturing industry that leading companies like Nissan are expanding their production in the UK."
Nissan said the new hatchback, which will be named closer to its sales launch, will play a major role in the company's continued expansion.
Around 80,000 of the new hatchback model will be built annually, triggering the need for the Sunderland plant to launch an additional shift.
This will see both the factory's production lines operating around the clock for the first time in the plant's 26-year history, a move which will take manufacturing capacity beyond 550,000 units.
