Criminals given lengthy prison sentences should serve the full tariff, says the West Yorkshire Police and Crime Commissioner.

Mark Burns-Williamson said life should mean life for people such as Yorkshire Ripper, Peter Sutcliffe.

He was speaking on the day Court of Appeal judges heard bids by two killers to challenge whole-life sentences.

The legal challenges followed a European ruling such sentences were a breach of human rights, amounting to “inhuman and degrading treatment”.

The Government has maintained whole-life tariffs are “wholly justified in the most heinous cases.”

Tory MP Philip Davies, whose Shipley constituency includes Cullingworth and Denholme, has urged the Government to tell judges not to be influenced by Europe.

Mr Burns-Williamson said: “Generally speaking, people who are sentenced to prison terms of a certain length should see those sentences out, with reviews perhaps at the end of the sentence rather than midway through.”
