Two severely disabled men will go to the Court of Appeal later to try to change laws governing the right to die. Paul Lamb, from Leeds, was paralysed from the neck down in a car accident and wants a doctor to help him to die. The 58-year-old, who has taken up the case begun by the late Tony Nicklinson, is seeking a ruling that would give doctors a defence to a murder charge. The other man, known only as Martin, is seeking a change to the prosecution of assisted suicide.
