David Cameron tried to get the Daily Mail's editor sacked for being pro-Brexit
The Daily Mail had pushed its readers to vote to leave the European Union while Cameron and his Chancellor George Osborne were campaigning to remain.
Lord Rothermere, the inheritor of a newspaper and media empire which includes The Daily Mail, told the BBC programme Newsnight that apparently Cameron pushed for Dacre to be sacked during a private meeting in his No 10 Downing Street flat in Westminster.
Lord Rothemere said Cameron told him to persuade Dacre to "cut him some slack."
However, Dacre allegedly told Cameron that he would not change his or the paper's editorial stance because he was a 25-year strong Eurosceptic and he believed his readers were too. Newsnight then claimed a Westminster source told Dacre that Cameron was pushing Lord Rothmere to sack him.
Lord Rothmere claims this made Dacre "incandescent" and led to the paper ramping up its pro-Brexit coverage.
Former prime minister Cameron called for the EU referendum after promising voters that if they voted him and his Conservative party into power in the 2015 general election.
He explicitly said he was against leaving the EU, and instead would favour a renegotiation of Britain's current membership within the bloc.
Cameron tried to push for Britain to essentially opt out of the Freedom of Movement Act while still retaining the conditions of its current trading setup within the EU. However, after EU officials said "no," in no uncertain terms, his proposed deal was deemed as a failure.
When Brits voted by a slim majority for Brexit on June 23, he stepped down almost immediately afterwards and Theresa May became the leader of the Conservative party and the new leader of the country in July.
