Gina Miller has said a change of tone in the Daily Mail’s Brexit coverage “isn’t going to happen anytime soon” despite Geordie Greig taking over as editor.

Investment manager Miller is best known for issuing a legal challenge against the Government to give Parliament a vote on whether the Prime Minister could trigger Article 50 to take Britain out of the European Union.

She told the NCTJ’s Journalism Diversity Fund event in London yesterday that journalists “should be stepping up” with their reporting of the Government’s Brexit negotiations with the EU.
