The widow of an exiled Pakistani politician murdered outside his north London home has urged anyone who knows who his killers are to come forward.
Dr Imran Farooq, 50, a senior member of the MQM party who has been in London since 1999, was stabbed in Green Lane, Edgware, last Thursday.
His wife Shumaila Imran said his murder had "devastated me and left our family in a state of shock and disbelief".
The inquiry is being led by Scotland Yard's counter-terrorism unit.
Officers are working on the assumption that Mr Farooq's murder was politically motivated.
Speaking at a press conference at Scotland Yard, his wife said: "Imran was a dedicated family man, a loving father and a loving husband".
"Someone somewhere knows something about my husband's murder.
"It does not matter how insignificant this information may seem to you, it could be absolutely vital to the police investigation".
