The prime minister has urged MPs to back her Brexit deal, saying it is the only way to honour the referendum result and protect the economy.
Writing in the Mail on Sunday, Theresa May said her critics – both Remainers and Brexiteers – risk damaging democracy if they oppose her plan.
But a poll carried out for the People’s Vote campaign suggests fewer than one in four voters support her Brexit deal.
MPs are due to vote on whether to back Mrs May’s Brexit plan next week.
The UK is due to leave the EU on 29 March 2019 – regardless of whether there is a deal with the EU or not.
A deal on the terms of the UK’s divorce and the framework of future relations has been agreed between the prime minister and the EU – but it needs to pass a vote by MPs in Parliament before it is accepted.
The House of Commons vote had been scheduled to take place in December but Mrs May called it off after it became clear that not enough MPs would vote for her deal.
The debate on the deal will restart on Wednesday, with the crucial vote now expected to take place on 15 January.

Writing in the Mail, Mrs May said: “The only way to both honour the result of the referendum and protect jobs and security is by backing the deal that is on the table.”
She said “no one else has an alternative plan” that delivers on the EU referendum result, protects jobs and provides certainty to businesses.
“There are some in Parliament who, despite voting in favour of holding the referendum, voting in favour of triggering Article 50 and standing on manifestos committed to delivering Brexit, now want to stop us leaving by holding another referendum,” she said.
“Others across the House of Commons are so focused on their particular vision of Brexit that they risk making a perfect ideal the enemy of a good deal.
“Both groups are motivated by what they think is best for the country, but both must realise the risks they are running with our democracy and the livelihoods of our constituents.”
Public polled on Brexit
Meanwhile, a poll of more than 25,000 Britons suggests Labour would be punished by voters if the party either ends up backing the government’s deal or does not actively oppose it.
