An exiled Pakistani politician has been murdered outside his home in north London, party leaders say.
Imran Farooq, a senior member of the MQM party, is believed to have been attacked in Green Lane, Edgware.
Metropolitan police say a 50-year-old man died after suffering multiple stab wounds and head injuries. No arrests have yet been made.
Mr Farooq disappeared from Pakistan in 1992 and is known to have been living in exile in London since 1999, when he claimed asylum in Britain.
He is understood to have been wanted by security forces and said in 1999 he had spent the previous seven years in hiding in Karachi.
The MQM (Muttahida Quami Movement) is the dominant party in Pakistan's largest city, Karachi. Mr Farooq was one of its founding members.
