Prince Harry has revealed that reforming the British press is now his life’s work, a project he said his father – King Charles – has described as a “suicide mission”.

He said that following Jeremy Clarkson’s misogynistic attack on his wife in The Sun last month, it is a campaign for “accountability” which he is waging on behalf of the entire world.

He also said he believes that negative headlines against him are driven by intimidation on behalf of the UK’s three largest newspapers groups – the publishers of The Sun, Daily Mail and Daily Mirror – because he believes his ongoing legal actions could shut them down.
