A leading journalist has said Jeremy Corbyn produced a "hopeless" response to the planned increase in self-employed national insurance contributions outlined in Wednesday's Budget.
The hike continues to cause a stir in Parliament, with Labour MPs leading the criticism by accusing Chancellor Philip Hammond of breaking a pledge to freeze tax and NI contributions for the duration of this Parliament.
Matt Chorley, editor of the Times Red Box, told Julia Hartley-Brewer Labour's leader set a poor example in his response.
He said: "His [Jeremy Corbyn] response to the NI hike was pretty hopeless and I don’t think we should be overly surprised at this.
"The fact this self-employment tax raise was floating around the papers for a few days didn’t prompt anyone in [Mr Corbyn's] office to do up a side of A4 to tell him what to speak about.
"I spoke to a Labour source who was trying to get a line up and running on what the party position was on the self-employment changes.
"It took several hours before we heard anything from John McDonnell, saying they opposed the changes."
