WATCH: Former Labour leader tells Jeremy Corbyn to stop looking untidy
Speaking to RT's News Thing show on Friday night, Kinnock told an anecdote about the time his dad explained to him how important it is for politicians to looks "tidy."
Kinnock was responding to a question about the claim made by David Cameron in parliament last month, that his mother would tell Corbyn to "put on a proper suit, do up your tie and sing the national anthem."
Here's what Kinnock told RT:
"When I was getting engaged in political campaigning and so on in my teens and early twenties he [Kinnock's father] actually said to me one day, when someone had made a comment to him about a politician looking very untidy. I said "what the hell does it matter what people wear? It's about what they're thinking, what they're saying, what they're working for, Dad!" And he said to, they think, that for politicians, every day should be Sunday - you've got to look tidy'.
Asked whether he did actually agree was with Cameron's mum, Kinnock said he did as she seemed like a "fairly sensible lady."
"As long as it's Cameron's mum, who seems like a fairly sensible lady to me, OK, but not David Cameron, I couldn't possibly agree with him."
