The SNP has called for a cross-party opposition leaders’ summit to stop a no-deal Brexit by Boris Johnson.
The party’s Westminster leader Ian Blackford urged his counterparts in other parties to work together to prevent the “unmitigated damage” of the UK leaving the EU without an agreement.
PM Johnson has been left with a working majority of just one in the House of Commons after Thursday’s by-election defeat to the Lib Dems in Brecon and Radnorshire.
Blackford wrote to Labour’s Jeremy Corbyn, Plaid Cymru’s Liz Saville Roberts, the Liberal Democrats’ Jo Swinson, the Greens’ Caroline Lucas and Anna Soubry from the Independent Group for Change.
He wrote: “I ask that we use the summer, collectively, to coalesce against a no-deal Brexit. Time is short and we must act to prevent the prime minister destroying the futures of citizens up and down the country.
“If agreeable I will make arrangements immediately.”
There was a pact between some remain-supporting parties to allow the Lib Dem candidate Jane Dodds a free run in Brecon.
Labour ran but came fourth and Lib Dem leader Jo Swinson ruled out any electoral alliance with Labour, insisting that Jeremy Corbyn cannot be trusted on Brexit.
She said: “The Prime Minister is shamefully playing with the future of British families, businesses, consumers by keeping a chaotic no-deal Brexit on the table.
“The success of the Liberal Democrats in Brecon and Radnorshire was a clear rejection of no-deal. It is clear the Tories are out of touch and have no mandate. We can stop the UK crashing out of the EU if like-minded people work together.”
