Britain's former foreign secretary Boris Johnson says only he can see off both Nigel Farage and Jeremy Corbyn as he urges Tory MPs and party members to make him their next leader and prime minister.

The leadership campaign front-runner said he would refuse to pay the promised PS39 billion ($A71 billion) to the European Union unless better Brexit terms are on offer - and would step up preparations to counter no-deal "disruption".
Meanwhile leadership rival Michael Gove set out plans to replace VAT after Brexit with a "lower, simpler" sales tax.
And Sajid Javid's campaign received a boost with an endorsement from Scottish Tory leader Ruth Davidson.
In his first major interview of the campaign, Johnson told the Sunday Times he could defeat the twin threat posed by the leaders of the Brexit Party and Labour - comparing them to the sea monsters from Greek mythology which troubled Odysseus.
"I truly believe only I can steer the country between the Scylla and Charybdis of Corbyn and Farage and on to calmer water.
"This can only be achieved by delivering Brexit as promised on October 31 and delivering a One Nation Tory agenda."
On Brexit, he said he would scrap the backstop - something the EU has so far refused to do - and would settle the Irish border issue only when Brussels is ready to agree to a future relationship.
The PS39 billion settlement would only be paid when there is "greater clarity" about the way forward, he said.
"I always thought it was extraordinary that we should agree to write the entire cheque before having a final deal," he said. "In getting a good deal, money is a great solvent and a great lubricant."
The former foreign secretary received backing from prominent Brexiteer Steve Baker - who had been considering his own leadership bid.
He also picked up endorsements from Cabinet ministers James Brokenshire, Chris Grayling and Alun Cairns, and former international development secretary Priti Patel.
Gove sought to focus once more on policy issues after the revelations about his past cocaine use.
Writing in the Sunday Telegraph, he set out a "pro-business economic plan" to take on Corbyn's "Marxist message".
Gove said his plan would mean "reducing the regulations which hold business back", cutting taxes and "using the opportunity of life outside the EU to look to replace VAT with a lower, simpler sales tax".
As Theresa May resigned as Tory leader on Friday, the starting gun was fired for the race to replace her.
The nomination process will take place on Monday, with candidates requiring eight MPs to back them in order to enter the race, with the first round of voting on Thursday.
