talkRADIO presenter George Galloway believes Jeremy Corbyn has not been given the opportunity to explain his policies as infighting within the party continues.
Galloway's comments come after Labour leadership candidate Owen Smith made pledges on Wednesday including introducing wealth taxes, scrapping the Department for Work and Pensions and ending austerity.
"[Owen Smith] is a pound shop Neil Kinnock, so never one word where 100 words will do," former MP Galloway told Sam Delaney. "Kinnock was full of hot air.
"These are all already Labour party policies.
"The fact that nobody heard them was because people like Owen Smith have been swarming around Jeremy Corbyn trying to knife him.
"If he's so left-wing, why's he trying to get rid of the most left-wing leader Labour has ever had?
"The Owen Smith campaign is dead in the water.
"People don't believe he's sincere, they believe it's [just] Neil Kinnock-style rhetoric."
