UK religious leaders has joined forces on Sunday to say they are “deeply concerned” by draft legislation to legalise assisted dying that Members of Parliament will vote on this week.

Two new polls ahead of Friday’s parliamentary vote showed a majority of Britons support changing the assisted dying laws.

The House of Commons will get a free vote on Labour lawmaker Kim Leadbeater’s private member’s bill, allowing them to vote with their conscience.

If approved, the legislation, which would only affect England and Wales, would advance to further votes in both chambers of parliament.

The issue, which was last voted on in 2015, when MPs overwhelmingly rejected changing the law, has sparked concern from religious groups and other opponents about its implications
