Stephen Sedley, a former court of appeal judge, responds to an article by MPs Diane Abbott and Edward Leigh

While no one should underestimate the complexity of safeguarding (and Kim Leadbeater’s assisted dying bill, if anything, does the opposite), Diane Abbott and Edward Leigh inadvertently make the case for legalising assisted dying when they say that “the only adequate safeguard is to keep the law unchanged” (Our politics could not be more different – but we’re united against this dangerous assisted dying bill, 20 November).

The law as it stands is an inhumane set of traps. In 1961, it decriminalised suicide and then criminalised “encouraging or assisting” it – two different things. Encouraging suicide should continue to be a crime. The proposed reform is about whether it should continue to be a crime to assist a mentally competent adult to bring a dignified conclusion to a life that is approaching its end. If it is open to criticism, it is for leaving out individuals who face an incurable condition with no end in sight.
