Senior Tories fear the reverse will be the start of a series of defeats during the Lords Report Stage of the legislation with a hard-core group of Remain-backing peers tabling dozens more amendments.

New analysis released by Brexit campaigners last night revealed that 10 fanatical Remain-backing peers have proposed a total of 388 amendments designed to frustrate or reverse the EU departure process.

The research by the Change Britain pressure group, which wants a full break with Brussels, showed that Labour peers Lord Judd and Lord Adonis along with Lib Dem Lord Wallace of Tankerness had tabled the most amendments.

Gisela Stuart, chairman of Change Britain, said: "It’s deeply dissapointing that these peers are using parliamentary procedure to pursue their own agenda of stopping Brexit. Whilst 17.4 million people voted to leave the EU, a handful of unelected Lords are presumptuous enough to believe they can overturn the result and keep us under Brussels control.

"Rather than refusing to respect the referendum result and trying every trick in the book to reverse it, peers should accept the democratic decision of voters and work to get the best Brexit deal."
