A retired GP accused of being responsible for 'hundreds of deaths' at Gosport hospital should be prosecuted, says the MP of one of the victims.

Dr Jane Barton, 69, has been accused of prescribing deadly doses of diamorphine - a powerful opiate painkiller - to patients when she worked at the hospital near Portsmouth in the 1990s.

The “brusque, unfriendly and indifferent” doctor is expected to be named as the person responsible for the shortening of possibly hundreds of lives, following a £13 million investigation, according to a report in The Sunday Times.

Inquests in 2009 and 2013 into 11 of the deaths ruled medication prescribed by Dr Barton had contributed to six patients dying.

Dr Barton was found guilty of "multiple instances of serious professional misconduct" by the General Medical Council in 2010 but was not struck off and soon retired.
