Father and two young sons found dead on beach 80 miles from mother's body

The bodies of two young boys and their father were discovered at the foot of cliffs on the south coast an hour before their mother was found dead more than 80 miles away.

Scotland Yard said a murder investigation had been launched after the woman, believed to be in her 40s, was found with stab wounds at her home in south west London shortly before 6pm yesterday.
