Emily Thornberry has accused Boris Johnson of being part of a “vicious band” of global populists led by Donald Trump .
The shadow foreign secretary said she hoped the “long, global nightmare” of Mr Trump’s presidency would end if he was defeated by his Democrat rival in November’s US elections.
Ms Thornberry, who has announced she will stand in the Labour leadership contest, predicted this could also “turn the tide” on support for his right-wing international allies.
In a Facebook post on her priorities for the year ahead, she said: “I hope in November our long global nightmare will be over and Donald Trump will be dumped out of office by the American people, and we will finally see the United States resume its role as a global leader on the issues that matter to us all.
“What’s more, Trump’s defeat would hopefully turn the tide on his vicious band of so-called ‘populist’ imitators around the globe, including our current PM.”
The Labour MP plans to “shame” the Government into finally taking a stand on human rights abuses in countries like Myanmar, China, Brazil and Saudi.
She accused ministers of “turning a blind eye” when it was their trade partners or strategic allies responsible.
And she urged Australia’s government to wake up to its “wilful inaction” over climate change – which is behind the extreme weather events that have led to devastating wildfires.
Ms Thornberry is one of two MPs to have already declared in the race to take over from Jeremy Corbyn .
The other, Clive Lewis, yesterday urged other candidates not to turn on one another.
“When you’re hanging by the fingernails on a cliff edge, it’s usually not a good time to start fighting with those dangling with you. Far better is to help each other work out the way back up the cliff face”.
