Eleven police officers or staff are under criminal investigation over their handling of child sex abuse allegations against late politician Lord Greville Janner.

The peer, who died aged 87 in December, is alleged to have abused children over a period spanning more than 30 years and dating back to the 1950s.

Police watchdog the Independent Police Complaints Commission has told 11 individuals that they are under investigation for both alleged criminal offences and gross misconduct, as part of an inquiry into Leicestershire Police's handling of the claims.

It would not reveal how many are police officers and how many are staff.

In January, a report by High Court judge Sir Richard Henriques found that failures by police and prosecutors meant three chances were missed to charge Lord Janner.
