Shadow chief secretary to the treasury Peter Dowd had an awkward moment on Sam Delaney's show when quizzed about Labour's plans for the highest earners.
Dowd was speaking hours after the publication of Labour's manifesto, which proposes a sharp increase in income tax for those earning over £80,000.
But Dowd was unable to tell Sam Delaney how much more tax the highest earners would have to pay when pressed by our presenter.
The Bootle MP responded "I don’t have that figure in front of me at the minute, I could fairly easily calculate it."
He also told Sam Delaney people in the UK want to pay their fair share of tax and the highest earners will be prepared to pay more income tax to help rebuild the country.
Dowd added that that the manifesto clearly sets out where money for the pledges will come from, despite the Tories claiming it doesn't add up.
