Secretary of State Rex Tillerson will go ahead with a planned trip to Moscow to deliver a “clear and co-ordinated” message to the Kremlin over its support for Bashar Assad’s Syrian regime.
But the move makes the Foreign Secretary look like “some sort of mini-me” who cannot be trusted to hold his own talks with Russian counterpart Sergey Lavrov, Alex Salmond said.
The SNP’s foreign affairs spokesman told BBC One’s Andrew Marr Show: “Boris Johnson just looks daft.
“What is the argument for not going ahead with a visit? Rex Tillerson is going on Wednesday so it can’t be that we have moved to a Cold War position of no talking whatsoever.
“The idea the Foreign Secretary can’t be trusted because he might pursue his own line or have an independent thought or crossover what the Americans are going to say just makes him look like some sort of mini-me to the United States of America.
“That’s not a position any Foreign Secretary would want to be in.”
“Boris Johnson looks in deep political trouble this morning,” he added.
Russia has consistently denied that Syrian forces used chemical weapons, insisting the incident at Khan Sheikhoun was caused by a hit on a rebel chemical weapons plant, a claim dismissed by the West.
Mr Johnson will push leading nations to demand Russia withdraws its forces from Syria when he meets G7 counterparts for talks in Italy next week.
International Development Secretary Priti Patel said Mr Johnson was focused on working with allies to find a solution to the crisis.
She told Marr: “This isn’t just about one voice, this is about the international community coming together and our Foreign Secretary is working with his American counterpart as that is the right thing to do.”
Pressed on why the UK had pulled out of talks with Moscow, she replied: “We are constantly engaging with all our counterparts and there has been dialogue. The Foreign Secretary has engaged his counterpart previously as well.”
