Debate over assisted dying in Britain intensified today following a healthy but heartbroken mother's moving account of her decision to end her life at a Swiss clinic.

Wendy Duffy, 56, is physically healthy and of sound mind – but so devastated by the loss of her only child in a tragic accident that she has decided to take her own life at the controversial Pegasos 'suicide clinic' this week. 

She told the Daily Mail: 'I want to die, and that's what I'm going to do. My life; my choice.'

Read the full exclusive interview with the Daily Mail here, in which she explains in heart-rending detail the reasons behind her decision that was a year in the making.

It comes as the Terminally Ill Adults (End of Life) Bill is not expected to pass during this parliamentary session because the House of Lords will run out of time tomorrow to debate all the legislation.

Now you can have your say on assisted dying in the Daily Mail's latest poll:

In yesterday's poll, Mail readers were asked: 'Do you agree with the smoking ban for Brits born after 2008?' Out of more than 4,000 votes, 57 per cent of you said 'no' and 43 per cent said 'yes'.
