Today Mr Johnson repeated his views on Britain leaving the EU and suggested that people “focus on the issue that really matters” rather than speculations over his political ambitions.
He said: “There’s always going to be a lot of bickering and moaning, but what I hope is that people will focus on the issue that really matters and that’s the one that’s going to be put to the people of this country in a few months’ time.”
Speaking outside his London home on Sunday Mr Johnson announced he was backing an EU exit.
“The last thing I wanted was to go against David Cameron or the government, but after a great deal of heartache I don’t think there is anything else I can do. I will be advocating Vote Leave … because I want a better deal for the people of this country to save them money and to take back control,” he said.
Mr Johnson’s support to leave the EU was seen as a blow to the Prime Minister, who has launched a major push to win support for his call to keep his country within the EU.
The Prime Minister will address the Commons at 3.30pm today after a tumultuous week in which he struck a deal for a reformed Europe and announced 23 June as the date for the EU referendum.
