It comes after a tape of a candid speech in which he warned of a Brexit meltdown and called the Treasury 'the heart of Remain' was leaked.
He claimed that the President would do a good job of handling the Brexit negotiations.
The phone call saw Mr Johnson reiterating that he was ‘like almost 100% sure’ that Russia was behind the Salisbury poisoning.
The Foreign Secretary accused the Labour leader of lending ‘false credibility’ to Moscow.
Russia is broadcasting 21 separate conspiracy theories over the Salisbury spy poisoning, according to Boris Johnson. The Foreign Secretary said that the Kremlin have been ‘pumping out a deluge of lies’ ever since spy Sergei Skripal and daughter Yulia were taken to intensive care following the nerve agent attack.
Foreign secretary Boris Johnson said it was "overwhelmingly likely" that Russian president Vladimir Putin ordered the attack on Sergei Skripal.
Foreign Secretary Boris Johnson has suggested that a bridge should be built between Britain and France.
The British government is considering ways to free Nazanin Zaghari-Ratcliffe from jail in Iran.
Simon Stevens will cite the Leave campaign's claim that Brexit will allow £350 million to be spent on the NHS to argue for more funding.
Several MPs say Boris Johnson should resign as foreign secretary following his latest gaffe.
Boris Johnson is a dilettante, trifling with diplomacy. If that were ever in doubt - or if anyone again attempts the ‘intellectual passing himself off as Bertie Wooster’ defence - we need only consider his handling of the case of Nazanin Zaghari-Ratcliffe, an Anglo-Iranian dual national imprisoned in Tehran. The Foreign Secretary, who should be fighting for her release, has instead risked prolonging her sentence, showing the same level of care when it comes to British citizens detained abroad as he did when he shoulder-barged a ten-year-old in a game of street rugby.
Theresa May has given up any notion of Cabinet discipline. In Priti Patel’s case, this extends to actually holding secret bilateral meetings with the prime ministers of foreign states, alongside lobbyists for their interests. While on ’holiday’ in Israel this summer - she clearly has a very unique notion of what constitutes a holiday - the international development secretary met Benjamin Netanyahu, as well as Yuval Rotem, from the Foreign Ministry, Gilad Erdan, minister for Public Security, Information and Strategic Affairs, and Yair Lapid, leader of the Yesh Atid party.
The Foreign Secretary has come under fire from critics who believe his style is not suited to someone in high office.
Michael Fuchs, deputy chairman of Mrs Merkel's CDU/CSU group in the German parliament, said the Foreign Secretary believes the offer Theresa May has made is “too much”.
Theresa May is facing calls to give Boris Johnson the sack in order reassert her authority over a fractured Conservative Party. Speculation is circulating that the Prime Minister is planning a cabinet reshuffle to shore up her position, with the Foreign Secretary in the firing line for a demotion. Supporters of the Foreign Secretary have also said that the PM lacks the authority to push him out of the door after her general election gamble backfired, leaving her without a majority.
