UK PM Andy Burnham has described the death of former Cambridge professor Jason Arday as “a tragedy on so many levels”, as he called for a “moment for reflection”.   Arday was found dead at a property in south London on Friday afternoon. He had resigned from his role at the University of Cambridge last week after allegations of plagiarism and questions about some of his achievements.   He had denied the claims.   Tap the link in @BBCNews’s bio for more.   #AndyBurnham #BBCNews
