BRADFORD, ENGLAND - JUNE 29: Foreign Secretary William Hague arrives for the first coalition cabinet meeting outside London at the Bradford Bulls Stadium on June 29, 2010 in Bradford, England. The prime minister is continuing the practice, revived by predecessor Gordon Brown for the first time since the 1920s, of hosting cabinet meetings away from London.

… allegedly. Well now the Daily Mail reports:

One of the women accused of being a Russian spy in the U.S. travelled on a British passport, according to the FBI.

Tracey Lee Ann Foley, who was posing as a naturalised U.S. citizen born in Canada, is believed to have been given forged British documents by her Russian handlers.

Now hang on; when the British government was so convinced that Mossad had used forged British passports to assassinate a Hamas arms dealer in Dubai, they went absolutely ape-s**t and an Israeli diplomat was ‘sent home.’
So, despite there being a different government, and given that successive administrations tend to take the same view. Indeed, William Hague supported David Miliband’s actions as Foreign Secretary in this statement to parliament:

“.. we cannot permit the cloning of, interference with or misuse of British passports by another state.”

So when does the Russian diplomat go home then, Mr Hague?
If they do take the same action as they did against Israel, fair enough; but if not, why?
