Several MSPs, including Liberal Democrat Liam McArthur, are attempting to pass legislation at the Scottish Parliament to provide those who are terminally ill with medical assistance to take their own life. Campaigners believe that the UK could be at a tipping point for legalizing assisted dying and have gained support from high-profile figures such as Dame Esther Rantzen and Dame Prue Leith. Rantzen has called for a debate on assisted dying in Parliament and has joined the Dignitas assisted dying clinic in Switzerland as an option in case her health does not improve. A Deltapoll shows strong public support for assisted dying to be made legal, with 71% in favor and 13% opposed. Rantzen has urged MPs to hold a free vote on the issue, stating that the public feels it is important to have a choice and not have their families watch them suffer.
