Brian Walden, the TV interviewer and former Labour MP, has died at the age of 86.

The broadcaster was known for his tough political interviews, including with Margaret Thatcher in 1989 which helped speed up the then-prime minister’s downfall.

Mr Walden died following complications from emphysema at his home in St Peter Port, Guernsey, on Thursday.

His widow, Hazel, said he was “always happy and got on well with people”.

Mr Walden served as Labour MP for Birmingham Ladywood from 1964 until 1977.

He was best known politically for an impassioned speech calling for the abolition of capital punishment.

Mrs Walden, who says she was “happily married” to him for 43 years, said her husband was a passionate Brexiteer and that his biggest regret would be that he had not lived to see Brexit.

She said: “He agreed with Nigel Farage that the only way is out, unless we wish to give up our British rights and tradition to be held in a superstate.”

After being elected as a Labour MP in four elections, he resigned from Parliament to become a journalist and broadcaster.

He presented the ITV political programme Weekend World as well as other TV shows including The Walden Interview and Walden.

He became known for his tenacious interviewing style, and often grilled the then-prime minister Mrs Thatcher. According to the Press Association, Mrs Thatcher enjoyed being interviewed by him.

During his most famous interview with her in October 1989, Mr Walden asked Mrs Thatcher: “You come over as being someone who one of your backbenchers said is slightly off her trolley, authoritarian, domineering, refusing to listen to anybody else – why? Why can’t you publicly project what you have just told me is your private character?”

The then-PM replied: “Brian, if anyone’s coming over as domineering in this interview, it’s you. It’s you.”

‘Able to read politicians’ minds’

Mr Walden won several awards for his broadcasting, and was named ITV personality of the year in 1991.

His friend John Wakefield, who he worked with at ITV, said the pair had a “terrific time” together.

“Brian was an immensely lively and entertaining person to work with,” he said.

“He was very much a team guy who loved what everybody had to say, including the most lowly, recent researcher, and was hugely gregarious and fun.

“He was brilliant because he was such a fantastic public speaker and, as a former politician, he knew how they operated – he was able to read their minds.”

Mr Walden later presented BBC Radio 4’s A Point of View programme, as well as documentaries for the BBC including Walden on Heroes and a series of profiles on former Labour Party leaders.
