London Mayor Sadiq Khan has been fined after being convicted over an untaxed Nissan Micra, despite City Hall saying the vehicle does not belong to him or Transport for London.

Khan was convicted in his absence last month through the Single Justice Procedure, a fast-track system used for lower-level offences. He was ordered to pay a £220 fine, £85 in costs and £35.84 in unpaid vehicle tax.

The case concerns a 24-year-old blue Nissan Micra whose vehicle tax had expired. However, City Hall officials say neither Khan nor TfL owns or keeps the car, raising the possibility that the mayor was wrongly identified as its keeper.

The case has attracted further attention because DVLA correspondence addressed to Khan was reportedly sent to a nearby Gordon Ramsay restaurant rather than the TfL offices. The DVLA has now confirmed it is reviewing the circumstances surrounding the prosecution.

Khan has said he believes he is the victim of a scam, with City Hall pointing to previous incidents in which vehicles were allegedly registered using his name. The controversy also renews scrutiny of the Single Justice Procedure, which has faced criticism over convictions being issued without defendants appearing in open court.

The unusual case could now become a wider debate about vehicle-registration fraud, DVLA procedures and safeguards within Britain's fast-track justice system.
