GB News fan-favourite Tom Harwood has taken matters into his own hands by cleaning graffiti from a London Underground train whilst delivering a scathing critique of Mayor Sadiq Khan's handling of vandalism on the transport network.

The broadcaster filmed himself scrubbing a Bakerloo line carriage, declaring: "So have a look at what we've been doing to this tube train. As we know, the Bakerloo line is absolutely riddled with graffiti."

Tom's intervention comes as Transport for London has acknowledged "a significant increase in the number of graffiti incidents" across the network, with the Bakerloo and Central lines experiencing the worst damage.

The cleaning process proved remarkably straightforward, according to Tom. "What we did was, we sprayed the graffiti with anti-graffiti spray, eco-friendly anti-graffiti spray, then a bit of scrubbing," he explained.

"It just comes off. This is not rocket science. You'd think that TfL would employ some people to do this. If TfL won't, we thought we'd go and help show how it's done."

The presenter and his companions carried out the cleaning whilst the train remained in service. "The train is moving as we scrub. It's on the Bakerloo Line which is one of the worst for graffiti," Tom noted.

He emphasised that the vandalism problem had escalated recently, stating: "Only in the last year or two have we started to see really intense amounts of graffiti."

TfL has confirmed that technical difficulties at their depot have hampered cleaning efforts. The transport authority explained that "a track defect in the depot meant we were unable to use our automatic train wash for a few weeks," forcing them to rely on manual cleaning which "takes a significantly longer amount of time."

The track defect was repaired approximately two weeks before TfL responded to a Freedom of Information request. Since then, "all our fleet has been washed externally and the overall condition of the fleet is beginning to improve," according to TfL.

When Transport for London was established in 2000, commissioner Bob Kiley implemented a "broken window" policy towards vandalism, based on the principle that addressing minor crimes would prevent more serious offences.

Tom received support from tube drivers during his cleaning efforts. "One tube driver actually told us when a particular train would come back round again so we could complete our work. The two drivers we met were nothing short of really happy that we were there doing this work," he revealed.

The presenter delivered a broader critique of London's governance, stating: "This displays a total lack of imagination, a total unwillingness to do anything about the sort of social decay we're seeing in our cities."

He concluded with a direct message to the Mayor: "You don't have to live with this social decay. You can come up with new ways to do things. Pull your socks up, Sadiq, do something about it."
