Angus Robertson has warned Theresa May her “days as Prime Minister of a United Kingdom are numbered” if she “continues to ignore” Scotland.
The SNP’s new deputy leader suggested that “refusing to even consider” Scotland’s role in the EU would trigger a second ballot.
Addressing the SNP conference in Glasgow, the Moray MP also announced that the SNP would use an opposition day debate in Westminster to argue for the protection of EU nationals’ rights to stay in the UK after Brexit.
Referring to comments by Conservative minister Liam Fox, Mr Robertson told the conference: “In contrast to the work taken by our First Minister and the Scottish Government to reassure EU nationals living in Scotland, the UK Government has referred to them as cards to be bargained with. How shameful.”
His speech to conference followed Ms Sturgeon’s announcement on Thursday that a Bill for a second independence referendum will be published for consultation next week.
Mr Robertson added: “Theresa May says that options for keeping Scotland in the EU are impractical, that we’ve had our referendum and that there will be a UK approach to Brexit.
“She refuses to accept that for Scotland, for us, remain means remain.
“My message to the Prime Minister is this: if you continue to ignore the express will of the people of Scotland, if you refuse to even consider how we might protect Scotland’s place in the EU, then be in no doubt, your days as Prime Minister of a United Kingdom are numbered.”
