The case of a paralysed man who wants doctors to be able to take his life without fear of prosecution is being heard at the High Court.
Tony Nicklinson, 58, from Wiltshire, has locked-in syndrome following a stroke seven years ago.
The hearing represents a fundamental challenge to the law on murder, the BBC's Fergal Walsh reports.
