A British official says the government is to expel an Israeli diplomat following the use of fake British passports in the suspected Mossad assassination of a Hamas operative.

Foreign Secretary David Miliband is scheduled to address Parliament on Tuesday on the issue.

His office declined to provide details in advance. A government official, speaking on condition of anonymity because he was not authorised to comment ahead of the statement, says Britain will expel one Israeli diplomat.

Israel’s ambassador to Britain Ron Prosor was called to London’s Foreign Office on Monday for talks.

Britain sent investigators to Israel this month to meet eight Israeli-British dual nationals whose identities were used in the January 20 slaying.
