Gallagher, who grew up with his brother Liam in a working-class area of Manchester, said he would never vote for the Tories because they "don't care about the vulnerable" but added "communists don't care about the aspirational".
The 48-year-old was interviewed by Julie Burchill in The Sunday Times. When asked what he thought of Corbyn, he said: "I don't like communism."
Gallagher, who was famously invited to Downing Street by Tony Blair to solidify New Labour's vibrant, cool, image, said the party disappointed in power after 1997.
He said: "Speaking as somebody from the left, I thought the New Labour years, coming up to 1997, were amazing. It was so exciting to be in England at the time, because there were so many things going on.
"But then, the Labour Party proved themselves to be 'Meet the new boss, same as the old boss', and until that changes, I'm not having it. The Tories don't care about the vulnerable, and the communists don't care about the aspirational."
He added: "I could never vote Tory because some invisible force field would stop me from putting my vote in the ballot box."
