Protesters have gathered outside Parliament as MPs begin a debate on controversial 'right to die' laws.
Campaigners from both sides of the debate held placards and voiced their views ahead of the Commons discussion.
Labour MP Rob Marris introduced the Assisted Dying Bill, the first key question of conscience for the new House of Commons.
Opening what is expected to be a lengthy debate, Mr Marris said social attitudes have changed in the past 50 years.
"This debate is not about opinion poll numbers, it's about a matter of conscience and ethics and the kind of society in which we live," he said.
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.
