One MP was reduced to tears as she recounted her husband's suffering during the last years of his life, as the Commons continued to debate a bill on assisted dying.
Madeleine Moon's husband Steve died earlier this year after contracting a form of Motor Neurone Disease.
In an emotional speech, the Bridgend MP told how life "changed to being a burden".
She said the bill would not have helped him but that it should be allowed to go on to the committee stage.
"I believe that it is Parliament's job to look at the will of the people and to consider the difficult choices in front of society," she said. "We must be honest with the people and have that full and frank debate."
MPs have overwhelmingly rejected the Assisted Dying Bill, despite apparent public support.
MPs are set to vote on the right to die for the first time in 20 years today as controversial laws are subject to a landmark debate.
Described by the Archbishop of Canterbury as one of "the biggest dilemmas of our time", MPs are preparing to debate assisted dying.
