The 55-year-old comedian voiced his vision of politics that would “get the whole world of seven billion people all having a fair chance”.
Izzard, who is releasing a new memoir, Believe Me: A Memoir Of Love, Death And Jazz Chickens, told The Times Magazine: “I don’t really want to do the politics, but I think I have certain attributes.
“You have to be able to distil what are the essences of things that are going on, to see a positive vision forward.
“A lot of people with decent values will not go into politics because they feel they are going to get pummelled. I am proud of my country, but I want to reach out to other countries.”
He added: “I like Jeremy Corbyn. He believes in what he says.
“I would much rather have a Labour Party government than a Conservative one led by Theresa May.”
Izzard, who identifies as transgender, stated that he would be campaigning for Labour in “boy and girl mode”.
Speaking on the change of political understanding of transgender issues, he said: “I do feel we have crossed into a place of more political acceptance.
“It’s allowed now. I have boy genetics and girl genetics.
“That’s what I’m pushing for. I think I’ve got through the net now.”
