PEERS described the assisted dying Bill as so “demonstrably flawed” that it risks failing to become law.

A record of more than 900 amendments have been put forward to The Terminally Ill Adults (End of Life) Bill, which proposes legalising assisted dying for terminally ill adults in England and Wales.

It will become law only if both the House of Commons and House of Lords agree on the final drafting of the legislation, with approval needed before spring when the current session of Parliament ends.

Peers began their first of at least four days of detailed line-by-line scrutiny of the proposals today.

Baroness Gisela Stuart said there are “so many flaws” with the Bill in its current form “that I don’t think this house, however long we debate it, can actually get it to a stage where it is legislatively fit to be passed, and that is our role.

“We should not vote for anything that cannot legislatively be properly implemented.”

Lord Andrew Tyrie added that while he is a supporter of the Bill’s intentions, it is “demonstrably flawed,” suggesting the government must take more control of the draft legislation.

He added: “They need to consult nationally. They need to consult widely. They need to try and find as much consensus as possible, and then in a considered way, they need to come back to the house.

“I think attempting to deal with these 900 amendments in this way is going to end up with the Bill being talked out.

“It’s going to end up with us in a place we don’t want to be — at least those of us who want to see progress on this Bill.”
