Boris Johnson trousered almost £43,000 for a speech in Switzerland which he used to back a No Deal Brexit .
The eye-watering figure was paid to the Tory leadership frontrunner for an address to the Swiss Economic Forum on May 24 - the same day Theresa May announced her resignation.
Experts say a no deal Brexit could cost thousands of jobs, and Chancellor Philip Hammond announced it could inflict a £90billion hit on the UK economy.
But at least millionaire Mr Johnson - who also earns £22,000 a month from a Daily Telegraph column - managed to turn a profit.
Legal disclosures show he earned £42,580 for just three hours' work, a rate of £14,193 per hour, plus free travel.
"We will leave the EU on October 31, deal or no deal," Mr Johnson told the conference.
He added: "The way to get a good deal is to prepare for a no deal situation.
"To get things done you need to be prepared to walk away."
Mr Johnson "prohibited image and sound recordings" of his comments at the conference, according to a Swiss news report, but one attendee posted a photo anyway
Days earlier, he was paid another £25,540 for another private speech - which he used to announce his own leadership bid.
He told the event in Manchester by the British Insurance Brokers Organisation: "Of course I'm going to go for it."
New figures show mega-rich Tory donors are flocking to back the overwhelming favourite for Prime Minister.
Mr Johnson has registered £235,000 in the last two weeks, taking the total amount he has received in the last year to £502,000.
The most recent donations include £50,000 from Peter Cruddas, one of the City of London's most prominent Brexiteers, and £50,000 from James Reuben, a financier.
By comparison, Hunt registered no additional donations in the last two weeks.
