David Martin, of Scottish Labour, said he was “heartbroken” by the prospect of Scotland being made to leave the EU after the UK-wide referendum.
Nicola Sturgeon has constantly used Brexit as a springboard to launch a second independence referendum after the SNP were defeated in their first attempt in 2014.
Mr Martin, speaking at the European Parliament in Strasbourg, claimed the rest of the UK’s decision to quit the EU has left the entire UK’s future “hanging by a thread”.
He said: “In September 2014, I voted to keep Scotland in the UK. In June 2016, I voted to keep the UK in the European Union. Today I face the reality that Brexit will remove my country from one union and leave the other hanging by a thread.
A Scottish Labour MEP said Brexit would destroy the UK
The UK will not only be leaving the EU, the UK will not exist any longer
“Scotland voted overwhelmingly to remain in the EU. Edinburgh, a city I have represented in this house for 33 years, voted 75 per cent to remain.
“The feeling in Scotland is that we are being dragged out of Europe against our will – a feeling only compounded by Mrs May’s determination to pursue a ‘hard’ Brexit, for which she has no mandate.
“The resolution we are about to vote on recognises this face but provides no solution. The Council document calls for flexible and imaginative solutions to be found for Ireland.”
Requesting the UK Government listen to Scottish demands, Mr Martin added: “In conclusion, if the UK is not flexible in these talks, the UK will not only be leaving the EU, the UK will no exist any longer.”
Mr Martin’s comments come at a time when Ms Sturgeon’s independence dream is leaving Scotland’s economy teetering on the brink of recession.

Scottish Tory finance spokesman Murdo Fraser warned the country was “facing a crisis”, insisting Ms Sturgeon “must take responsibility for this mess”.
He added: “She has made Scotland the highest-taxed part of the UK and created more instability and uncertainty with her threat of a second referendum. Now we see the real-life impact of her mismanagement.
“More than ever, Scotland needs a First Minister in charge who gets back to her desk, ends her obsession with a second referendum and focuses on her day job.”
