Boris Johnson, who is now the overwhelming favourite to become the next Tory leader and succeed Theresa May as Prime Minister, castigated former Labour leader Gordon Brown for not seeking an immediate mandate from the British public after he inherited the top job from Tony Blair in 2007 - comments which will surely heap significant pressure on Johnson to call an immediate General Election or be justifiably branded a rank hypocrite (not that he isn't already), should he indeed enter Number 10 without a public vote in July.
