James Cleverly has said it is "deeply, deeply unfair" to criticise the Prime Minister for her handling of Brexit.
Appearing on the breakfast show, the deputy Conservative Party chair said Mrs May had "inherited a situation not of her making".
"The idea that this situation can be laid at the feet of the Prime Minister is inaccuracte and deeply, deeply unfair," Mr Cleverly told talkRADIO's Julia Hartley-Brewer.

"She inherited a situation not of her making. The previous Prime Minister [David Cameron] said he wouldn't be able to do the job."
The politician's appearance on the breakfast show followed last night's meaningful vote, which saw the Prime Minister's Brexit deal defeated by a majority of 149.
"Last night was an opportunity for people who campaigned passionately for Brexit, we could have secured Brexit, got it done," Mr Cleverly said.
"Not perfection, but if you strive for perfection, you will be constantly disappointed in life."
