The British director John Madden says he does not believe there is "any harm" in people from the arts world expressing their views on President Trump.

He said: "It is hard to think of a political figure that has been more provocative and more divisive than the current President of the United States."

The actress Meryl Streep had "endured a lot of very visceral attacks of one sort of another since she spoke out about it" but her view had been she didn't have a choice, she had to speak out, said Mr Madden.

"What is the alternative? The alternative is not to say anything," he added.
