A 66-year-old man who raped a three-year-old boy has been jailed for life.
Barry John Britton, from Westminster, became friends with the victim's family earlier this year and they allowed him to babysit their young son.
But the boy's grandmother became suspicious and after speaking to her grandson she called police.
Detectives took evidence from Britton's home and after initially refusing to co-operate with police, he changed his plea to guilty.
Britton was sentenced at Southwark Crown Court.
