Reform UK would pledge to repeal the legalisation of assisted dying at the next election, The Mail on Sunday understands.
Nigel Farage’s party is expected to promise to reverse the law in its next manifesto, assuming the legislation passes in the Lords.
On Friday MPs narrowly voted the Bill through by 23 votes – 32 fewer than when they backed it in principle in November.
Under the current plans, assisted dying would not be available until 2029, giving opposition parties a window to reverse it, sources said.
Mr Farage and two other Reform MPs voted against the private member’s Bill on Friday. His deputy Richard Tice and newest MP Sarah Pochin voted for it.
The Reform leader has said: ‘I voted against the assisted dying Bill, not out of a lack of compassion, but because I fear that the law will widen in scope. If that happens, the right to die may become the obligation to die.’
He also described the Bill as ‘un-Christian in every way’.
Campaigners against legalising assisted dying are hopeful the Bill will be prevented from becoming law in the House of Lords.
A campaign source said: ‘Bearing in mind how dangerous this Bill will be for vulnerable people, it’s not unreasonable for different political parties to think about what might need to happen if it does become law.
‘If the leadership of a party is of the view that the legal status quo is dangerous, it would only be natural for them to want to scrap the system.’
It is also understood Reform would pledge to repeal the decriminalisation of abortion at any stage of pregnancy, voted through last week.
An insider said: ‘Each party will have to state its position on abortion and assisted dying in their manifestos. The
election is an opportunity to reverse them both.’
The change to abortion laws will mean women who terminate their pregnancy after 24 weeks will no longer be at risk of police investigation.
The law would still penalise anyone who assists a woman in getting an abortion outside the 24-week legal framework. Mr Farage said after the vote: ‘I am pro-choice, but I think it’s ludicrous that we can allow abortion up to 24 weeks.
‘Yet, if a child is born prematurely at 22 weeks, your hospital will move heaven and earth and probably succeed in [making sure] that child survives.’
