Zac Goldsmith will tonight take on Channel 4 news anchor Jon Snow in response to a report that questioned his spending during the election.

The report, aired last night, accused Richmond Park's MP of failing to account for money spent on his election campaign and claimed that an investigation by the Channel 4 News team and Bureau of Investigative Journalism had unearthed discrepancies in Mr Goldsmith's campaign spending.

Mr Goldsmith denied any wrongdoing and stated on his blog that Channel 4 had refused his right to reply to accusations and had not responded to his offer to film a live interview where he was willing to address the issues.

He wrote that he was "hoping to be able to tackle Jon Snow" after "Channel 4 refused [him] a right to reply" yesterday and maintained that the report itself was nonsense on every level.

A spokeswoman for Channel 4 said: "We informed Zac Goldsmith of our investigation last week, and he had ample opportunity to respond publicly to the important questions we put to him.

"We are delighted that he will be appearing on the programme tonight to do so."

In the report Mr Goldsmith was accused of exceeding the £11,003 limit on candidate spending during the 23 days between the dissolution of Parliament and the May 6 election.

Questions were raised about the amount that was spent on items like leaflets, signs and campaign jackets after some items were credited to different campaigns and some items ordered were allegedly not used.

Westminster watchdog the Electoral Commission confirmed it had received a dossier raising questions about campaign spending by the multi-millionaire Conservative MP.

An assessment now has to be completed before a decision will be taken over whether it is a case requiring an inquiry.

Mr Goldsmith insisted that investigations would find nothing out of order and wrote on his blog that the "formula we used is precisely the formula used by every candidate and MP across the land".

A Channel 4 News statement said: "Channel 4 News stands fully behind its report which was rigorously researched. The investigation into campaign spending continues."

Mr Snow's live interview with the MP will be aired on Channel 4 News tonight at 7pm.
