Sunak could become the UK's 57th Prime Minister tomorrow. Sunak and Leader of the House of Commons Penny Mordaunt are the only two in the race and Sunak is well ahead.
Meanwhile, the Liberal Democrats - who were the other half of the Coalition Government with the Tories between 2010 and 2015 - have called for a General Election...
The Liberal Democrats say the Conservative leadership contest has become "a total farce".
“This is a humiliating climbdown for Boris Johnson and all the Conservative MPs who wanted to put him back in Number 10," Lib Dem Deputy Leader Daisy Cooper says.
She says the public will "rightly be furious that they’re set to endure a third Conservative PM in just as many months".
“While people are struggling with their spiralling bills, the Conservatives look set to appoint a former chancellor who lost the country billions," she says.
She reiterated calls for a general election, saying the country doesn't need "another Conservative coronation".
