Donald Trump is a "bully, misogynist and a racist" and should not be offered a state visit to Britain, the deputy leader of the Liberal Democrats is expected to say.

Jo Swinson will warn of the return of the "politics of the bully", saying "Faragey, Trumpy, angry, arsey, shouty, slogans aren't a solution to anything".

Addressing the Lib Dem conference, Ms Swinson will outline a bold new approach to tackling populist politics, including a fresh vote on Brexit.

Ms Swinson is expected to say the US president is a product of "anti-liberal forces".

She will add: "Trump is a bully, a misogynist and a racist. He boasts about sexually assaulting women.

"He cruelly mocked a reporter for his disability. He has rolled back trans rights. And for someone who makes much of being straight-talking, he won't call a Nazi a Nazi.

"Yet the Conservative Government thinks it is right to offer Trump the honour of a state visit to the UK. They are wrong.

"It is a sign of our weakness in a Brexit world.

"How easily will our values be cast aside in our desperation to sign trade deals to avoid economic catastrophe."

At the party's conference in Bournemouth, Ms Swinson will say global politics seems broken "when calm heads and brave leaders are needed more than ever".

She will add: "A few years ago it would have seemed inconceivable that in such a crisis, China would be a voice of reason, and Russia more measured than America.

"The politics of the bully is back. Human rights are trampled. Climate change is denied. Hate and division are spread like poison into society."

The Lib Dem deputy leader will point to situations in North Korea, Turkey and Burma as evidence of global instability.

She will also highlight the regime in Venezuela, saying it "beggars belief that Jeremy Corbyn would rather defend a tenuous link to socialism than condemn these atrocities".

Ms Swinson will add: "We are absolutely right to fight for an exit from Brexit.

"Brexit will make it harder to follow our values, to protect human rights, to tackle climate change, to solve global problems.

"An exit from Brexit is necessary, but not sufficient.

"Because this culture clash continues, and the populists stoke this tension.

"They do it deliberately. They talk in simple soundbites that scapegoat different groups. It's all someone else's fault.

"As liberals we know this is nonsense. The Faragey, Trumpy, angry, arsey, shouty, slogans aren't a solution to anything.

"But we do need to offer our own alternative solutions. We need to be much more radical, both in what we propose and in how we craft it."
