MPs will take part in a rally to resist the weakening of end of life laws next month.

Care Not Killing, an alliance to promote palliative care and oppose euthanasia, is hosting the rally, which will feature speakers including Ann Widdecombe, Lord Alton of Liverpool, Jim Dobbin MP, Fiona Bruce MP and Dr Peter Saunders of the Christian Medical Fellowship.

Care Not Killing started in late July 2005 when a small steering group met in the lead-up to the debate in the House of Lords on assisted dying.

The group aims to promote better palliative care, to ensure the existing laws against euthanasia and assisted suicide are not weakened or repealed during the lifetime of the current parliament and influence public opinion on the issue.

Dr Peter Saunders, CEO of the Christian Medical Fellowship, said: "Any change in the law would put pressure on vulnerable people to end their lives. These pressures are intensely felt at a time of economic recession when many people, and the country itself, are under a lot of pressure. The right to die can so easily become the duty to die."

The mass lobby of parliament takes place from 10am to 4pm on 3 July at the Emmanuel Centre, Marsham Street, London. Visit the website for more details.
