On Friday, after weeks of fierce and passionate debate, MPs began their formal scrutiny of the bill that would allow terminally ill adults expected to die within six months to seek help to end their own life.
It was a day of tears, hope, relief and fear. This is the story of how it unfolded inside and outside of Parliament - and how Labour MP Kim Leadbeater secured a historic win for her proposed law.
It is nine in the morning. The MPs' debate hasn’t started yet but campaigners on both sides are already gathering outside the Houses of Parliament.
Those in favour of Leadbeater's bill are on the west side of Parliament Square, by the statue of activist Millicent Fawcett.
It is a sea of pink hats and pink jumpers, provided by the Dignity in Dying group.
Amanda, whose surname we are not using as with many of our other interviewees, has come from Brighton to be here. She has cared for people in their final stages of their life, including one friend with cancer.
She remembers her friend pleading with her to "kill me now, kill me now". "That’s an awful thing for someone to hear their loved ones say."
Another women called Sue is here, also wearing a pink hat. "I think this could be a momentous day," she says.
