Len McCluskey, general secretary of Unite, said: "It is with great sadness that we learn of Michael's death. He was a tremendous figure in the Labour movement, devoting his life to the advancement of working people and for that he will always be remembered with deep fondness.

"As a personal friend I always welcomed his views and guidance as well as his optimism and commitment to improving ordinary people's lives. He was a true friend of the trade union movement."

Peter Dean, Meacher's PA and office manager, told the Oldham Chronicle: "We are extremely sad and it has been quite a short illness he has had and we just don't know the details at present. He was such a well-respected person and we will just try to deal with any problems people in the area have ongoing. We will still try to assist in any way we can.

"We are extremely sad for his family but all of his staff here at his office have worked with him for 20 years so it is almost like a family bereavement for us. Our office usually deals with around 5,000 cases every year so he has impacted on an enormous amount of people's lives."
