Tory rebel Ms Soubry was also forced to reveal that pro-EU Tories face a grassroots revolt as they threaten to side with Labour MPs in a crunch Commons vote later today over the flagship Brexit Bill.
In a long-winded 3,200 plus-word statement on her constituency page last night, Ms Soubry admitted her defiance was angering senior Tories in her Broxtowe constituency, which voted to the Leave the EU by 52.5 percent.
She told how she has faced deselection calls if she failed to knuckle under and support Prime Minister Theresa May.
Under the title ‘Not giving in to threats’, she wrote: “A clearly co-ordinated campaign has seen a number of emails to Broxtowe Conservatives urging them to deselect me because they falsely claim I am trying to thwart or stop Brexit.
“Only one of these emails is from a constituent and none from members of the Conservative Party. They total 18.
“But they are effective in worrying association officers, many of whom would prefer an MP that didn’t trouble the whips and kept their head down on this most divisive of subjects.”
Hitting out at critics who have claimed she is trying to stop Brexit by supporting the House of Lords amendment for a ‘meaningful vote’, Ms Soubry said it was “critical” to put the UK’s interests above the loyalty of her party.
She wrote: “I believe Parliament, notably the House of Commons should have a meaningful vote in the event of us not getting a deal with the EU. It’s not revolutionary and neither does it make me a “traitor” as I have been called.
“Tomorrow, I will vote to give Parliament that “meaningful vote” and in so doing I will be voting against my Government.
“On Brexit, a subject that divides MPs within both main parties, I believe it is critical we put our country’s interest above loyalty to our party.
“To be frank I am getting a tad tired of being told I am trying to stop or thwart Brexit. I am not; I voted to trigger Article 50 which means we will be leaving the EU in March 2019.”
Ms Soubry revealed he had received death threats over her anti-Brexit stance and claimed the threats of deselection were a “threat to our democracy”.
She added: “The abuse and the threats of ‘de-selection’ continue and it is not only completely unacceptable they are a very real threat to our democracy.”
MPs are preparing to vote on an amendment to the Brexit Bill pushing to give Parliament a “meaningful” say on the final deal.
If the amendment passes, it paves the way for MPs to explicitly endorse an alternative to Mrs May’s plan for the UK’s exit from the EU.
This would weaken the Mrs May’s negotiating hand and make the prospect of crashing out of the EU with ‘no deal’ far less likely.
The Prime Minister staved off a Tory rebellion on the move last week but faces another bruising battle in the latest round of voting.
However, Brexiteers are increasingly confident the Lords amendment will be voted down.
