A Victorian MP has been taken away in an ambulance after collapsing at parliament during a marathon debate over controversial assisted-dying laws.
Upper house MPs sat through the night to debate amendments to the proposed laws, with opponents of the bill aiming to drag out the process for as long as possible.
It's understood the Labor MP collapsed in his office and paramedics transported him mid-morning on Friday.
The upper house was due to debate the bill all day and potentially into the weekend, but it has been suspended until a later date.
"The reason we're adjourning today is because of the health and wellbeing of one of the members of the chamber," Special Minister of State Gavin Jennings told parliament on Friday.
"We don't want to cause him or anyone else any stress in relation to this matter."
Premier Daniel Andrews said the lengthy sitting was "not an easy process to go through but we need to get this done".
"As I understand it, they are having a break ... given the health issues with one particular member of the chamber," Mr Andrews told reporters.
It was suggested to the premier it was "ridiculous" to expect politicians to work for more than 24 hours straight.
"Most people think politicians could probably work a bit harder, that would be my sense of it," Mr Andrews replied
Health Minister Jill Hennessy said the debate was mired as opponents dragged it out as long as possible to prevent a vote being called.
"Over the past 24 hours, there's been a degree of frustration more than emotion as we've been going through each clause," she told ABC Radio.
The Labor government has agreed to a series of amendments to the bill in a bid to get the 21 votes it needs in the 40-member upper house.
So far 20 MPs have said they will vote yes.
Under the first set of amendments to be considered, patients must be a Victorian resident for at least a year, the coroner will be notified and assisted dying will be mentioned on the death certificate.
