Kevin Tsujihara, chairman and CEO of Warner Bros, said: "Warner Bros has produced some of our most popular and successful films in the UK, working with British talent.

"The expansion of Warner Bros Studios Leavesden will allow us to further tap into the world-class creativity and innovation available here to continue this tradition of filmmaking excellence."

Culture Secretary Sajid Javid said: "For years the UK has been at the cutting edge of the creative industries - and we want that to be the case for decades to come. This comes back to two things - and the two things that I see being as the most important in my job.

"One: Promoting our culture. Music, film and television help inspire young kids and bring our country together - so I will always back those industries. And two: Our long-term economic plan."

Warner Bros president Josh Berger said the announcement confirmed its "commitment to the UK creative industries".
