Murder family win Blair's support

Police have an open mind about the motive

The prime minister has asked the Colombian president-elect to hand over two men police want to question about a stabbing in west London.

The two Colombians wanted in connection with the death of Damian Broom are claiming diplomatic immunity.

Mr Broom, 23, died after being stabbed outside a Tesco store in Greenford in May.

His family had petitioned the prime minister earlier on Wednesday to pressure the Colombians to waive diplomatic immunity.

'Hand them over'

Tony Blair raised the issue during talks at Number 10 with Alvaro Uribe.

I just want the law to be changed someway somehow because I wouldn't wish this on my worst enemy

Leonna McLoughlin, widow

Mr Blair's official spokesman said: "They discussed the murder of Damian Broom, with the president-elect being asked to consider urgently the waiving of diplomatic immunity for two Colombians the police want for questioning."

The spokesman gave no indication of the president's response.

Leonna McLoughlin, Mr Broom's widow, said: "I just want them to hand them over to our government because my child hasn't got a father right now and I've got no husband.

Vienna Convention

"I want something to be sorted, justice to be served.

"There's nothing they can do to bring him back but I just want the law to be changed someway somehow because I wouldn't wish this on my worst enemy."

The supermarket is a west London landmark

A military sergeant attached to the Colombian embassy, and his son, have voluntarily given an account of the incident to police and say they are not seeking to evade an investigation.

But they cannot be questioned under caution, or prosecuted, because of their diplomatic status under the Vienna Convention.

Human Rights lawyer Sadiq Khan said: "This situation is an absolute farce.

"Under the current law it would be possible for a foreign national to escape any criminal sanction on the basis of diplomatic immunity."

Mr Broom, a warehouseman from East Acton, west London, and a father-of-one, was chased by three attackers through the supermarket car park following a row in the drinks aisle.
