The Public Health Bill, which included proposals to ban the use of e-cigarettes in some public places, could fail tonight.
It comes after Plaid Cymru said it was withdrawing its support of the bill, after comments made by Public Services Minister Leighton Andrews AM in relation to another bill in the Senedd chamber earlier.
The Labour-led Welsh Government was relying on Plaid's support to pass the bill. Without their votes, the Assembly will be split 50/50 on the bill. It means as well as the e-cigarette proposals, that restrictions on tattooing and plans to improve access to public toilets will now also fail.
