It's a big day for ACT leader David Seymour today as his End of Life Choice Bill faces judgment from his fellow MPs.
The bill - that would give the terminally ill the right to choose to die - faces a make or break vote in Parliament.
It will either edge closer to becoming law or be thrown out.
MPs will vote according to their own conscience, rather than by party lines. Mr Seymour is in our Wellington studio.
He talks to Corin Dann.
