JEREMY Corbyn and Ian Blackford have become the latest senior politicians to snub Donald Trump by announcing they will not attend the state banquet for the US President during his long-awaited state visit in early June.

The Labour leader said Theresa May was wrong to "kowtow" to Mr Trump, who had torn up international treaties and used "racist and misogynist rhetoric".

The SNP leader at Westminster said: “It is unacceptable that at the same time as Donald Trump promotes the poisonous politics of division and alienates communities, the Prime Minister sees it fit to roll out the red carpet for him." 

Their decisions to decline invitations from Buckingham Palace follow those from John Bercow, the Commons Speaker, and Sir Vince Cable, the Liberal Democrat leader, strengthening a united Westminster front against the decision to afford America's 45th President the honour of a full state visit.

Downing St said people could expect Theresa May to attend the state banquet. "The PM has spoken about how much she is looking forward to welcoming the President here and building a close relationship," said Mrs May's spokeswoman.

Security will be tight when Mr Trump visits Britain from June 3 to June 5 during which he will, accompanied by his wife Melania, also attend a ceremony in Portsmouth to mark 75 years since the D-Day landings alongside other national leaders.

In a statement, Mr Corbyn explained: "Theresa May should not be rolling out the red carpet for a state visit to honour a president, who rips up vital international treaties, backs climate change denial and uses racist and misogynist rhetoric.”

The Labour leader insisted that maintaining an important relationship with the US did not require the pomp and ceremony of a state visit.

"It is disappointing that the PM has again opted to kowtow to this US administration,” declared Mr Corbyn.

But he added: "I would welcome a meeting with President Trump to discuss all matters of interest."

The SNP confirmed Mr Blackford had also turned down an invitation to attend the state banquet.

The Highland MP said: “Rather than laying out all the pomp and ceremony of a state visit, Theresa May should instead be holding meetings to challenge the US administration and raise key issues.

Scotland holds close ties of family, history and economy with the people of the United States, which we are immensely proud of and will continue to champion.

"Whilst Theresa May panders to Trump, the SNP will not compromise on our core values of respect, equality and tolerance,” added Mr Blackford.

Earlier this week, Sir Vince and Mr Bercow made clear they would not be attending the state banquet.

Stressing his rejection of the invitation meant “no disrespect” to the Queen, the Liberal Democrat leader made clear British politicians should not be “hobnobbing with a man who is on record as a misogynist and a racist”.

Mr Bercow’s office declined to give a reason for his non-attendance.

The Herald has approached the office of Nicola Sturgeon, the First Minister, to see if she would attend the state banquet if invited.
