A nurse jailed for murdering four elderly hospital patients has lost his appeals against the convictions.
Colin Campbell, previously known as Colin Norris, was found guilty in 2008 of killing four women and attempting to kill a fifth by injecting them with insulin.
Doris Ludlam, 80, Bridget Bourke, 88, Irene Crookes, 79, and Ethel Hall, 86, were being treated on orthopaedic wards where Campbell worked in Leeds in 2002 and developed unexplained hypoglycaemia.
Campbell, who always maintained his innocence, was granted a fresh appeal earlier this year, but it was rejected by the Court of Appeal on Thursday.
During his original trial, prosecutors said Campbell was alleged to have been present when or shortly before each of the patients suffered hypoglycemia and, because of the rarity of such a cluster of cases happening within a short space of time, he must have been responsible.
He was also found guilty of attempting to murder 90-year-old Vera Wilby and sentenced to life imprisonment with a minimum term of 30 years.
