Sefton Central Labour MP Bill Esterson has paid tribute to John Moores Jnr who has died aged 83.
Mr Moores, who was son of the late Sir John Moores, founder of Littlewood's football pools, lived in Formby with his wife Jane.
Bill Esterson said he was shocked to hear of Mr Moores death.
Bill said: "From the point I was selected to stand for the Sefton Central seat John Moores became a good friend and advisor.
"He was tireless in campaigning for issues of social justice and looking after the interests of the community of Formby where he lived.
"He had a deep sense of social justice and was always concerned about other people.
"I spoke to him recently and he was in very good form, so this has come as a particular shock to me and members of the Labour Action Teams throughout Sefton."
Bill passed his sympathies on to Mr Moores' wife Jane, son Kevin and the rest of the family.
Bill said: "Lots of people knew John. He was a very down to earth man who was always willing to do anyone a good turn. That's just the type of man he was.
"John was always full of energy and up for campaigning on a variety of issues.
"We have lost a good friend, but I am sure that his passion for social justice will live on as he was an inspiration to me and many others who met him."
Formby Councillor Catie Page said she was devastated after hearing the news.
Cllr Page said: "John and Jane have been real friends to me and the Formby Labour Action Team over the years and we are all shocked and devastated at the news.
"John was a real character and he was always on hand to give his help and advice.
"Everyone in the Labour Action Team send their condolences to Jane and the rest of the family."
