This by-election has restored some confidence in Scottish Labour and reminded the SNP that they can take nothing for granted.
Fellow Labour MP Josh Fenton-Glynn also plans to vote no, having previously abstained."If you'd asked me at any point in my life what I thought of assisted dying, I'd have always said in favour," he told the BBC.
He has suggested a number of amendments to the bill, and claims he is "still open to supporting" the plans, but doubts it will change after Leadbeater blocked previous similar attempts."We see quite a few of the amendments which are specifically aimed at stopping coercion being opposed by the supporters of the bill," he said, adding: "I don't think chances to make the bill safer have been taken."The two MPs have added their names to a growing list of their colleagues who have suggested they will switch sides including: Tory former minister George Freeman, Tory MPs Mike Wood and Andrew Snowden, Lib Dem Brian Matthew, Labour's Jonathan Hinder, Reform UK chief whip Lee Anderson and ex-Reform MP Rupert Lowe.
Labour MP Debbie Abrahams and Tory MP Charlie Dewhirst, who abstained previously, will vote against.Labour's Karl Turner, who voted in favour at second reading, is now abstaining.
Tory MP David Davis has not announced how he plans to cast his next vote, but has publicly backed a number of amendments that would make sweeping changes to the bill.
Some MPs have also changed their stance, by supporting the bill. Minister Chris Bryant is understood to be backing it, having abstained in November. Labour MP Jack Abbott, who voted against last November, is also now likely to vote in favour.Labour won a Westminster by-election in this area less than two years ago with a majority of about 9,500.
And in the 2024 General Election they won the corresponding House of Commons seat by a similar margin.This time they squeaked through on a thin margin of about 600 votes. Their position does seem to have slipped - and the Scotland-wide polls would back this up.
Also, this is a Scottish Parliament seat. The SNP have been in government in Edinburgh since 2007, and by-elections can often prove difficult for the party that's in power.But, at least in the immediate aftermath of this result, Labour are unlikely to let those factors take anything away from their win.
