Transport for London will today publish a league table detailing some £23 million worth of congestion charge penalties which remain unpaid by foreign embassies.
At the top of the group is the American embassy who have racked up an impressive £2,735,245.
The Russian Federation have also worked hard, pushing the Japanese into third place with £1,849,260 in unpaid fines.
Of course when Ken Livingstone labeled the US ambassador a 'chiselling little crook' for refusing to pay the charge, he was swiftly reported to the Standards Board for England.
However, when Boris Johnson said that he would gladly slap an asbo on offending ambassadors, the resultant controversy mysteriously failed to surface.
Speaking at his first People's Question Time in Bromley, the Mayor said:
"I think it's the Geneva convention which prevents me from slapping an asbo on every single diplomat who fails to pay, I think it's an unbelievable scandal."The Swiss typically have come forward with trying to broker some kind of deal, I'm very keen that whatever deal we do should reflect the fact that these people are using London's roads. This is not a tax, this is a charge for the use of our roads, and I believe the diplomatic community should have the decency to pay it. I intend to stick to that decision."
The disagreement centres on whether the charge is considered a tax or a toll. Under international law, embassies are exempt from paying local taxation.
The charges if paid in full, could scale down the size of Boris's planned fares increase or give new hope to the transport projects recently abandoned by the Mayor.
However, with no new powers to resolve the claims, it will take more than one of Boris's imaginary asbos to bring the dispute to an end.
