QUADRUPLE killer Mark Hobson will have to wait to find out if he will spend the rest of his life in jail after he launched an appeal against his sentence.

The former binman, who admitted murdering his girlfriend, her twin sister and an elderly couple, was given a "whole of life tariff", which means he will never be released from jail.

At the Court of Appeal in London, Jeremy Richardson QC, for Hobson, argued his client should have been given credit for his guilty pleas in the setting of a tariff.

After hearing legal arguments, Lord Chief Justice Lord Phillips, sitting with two other judges, said they would rule on the matter at a later date.

Hobson, 36, admitted murdering his girlfriend Claire Sanderson, 27, and her sister, Diane, at his flat in Camblesforth, North Yorkshire, and killing pensioners Joan and James Britton at their home near York.

At Leeds Crown Court in May, the judge hearing the case sentenced Hobson to life in prison and gave him a whole of life tariff.

His case set a precedent because such a tariff had never been imposed on someone who had pleaded guilty.
