The widow of the first Briton to end their life at the Dignitas clinic in Switzerland said she felt "absolutely wonderful" after MPs voted in favour of a bill to introduce assisted dying.
Win Crew, from Liverpool, was speaking after the Assisted Dying Bill was passed in the House of Commons by 330 votes to 275, a cross-party majority of 55.
In 2003, Mrs Crew travelled to Zurich with her husband Reginald, who had suffered for four years with motor neurone disease (MND).
Beside his death bed, Mrs Crew, now 92, promised to campaign for a change in the law, and said she "never regretted the decision, because it's what Reg wanted."
