Rumours pollution on the River Thames by Richmond Bridge was caused by a Virgin Media marketing stunt have been quashed.

A specially modified black cab was driven across the river on Monday, September 22, to mark the launch of Virgin Media Business’s free cab service for small and medium-sized businesses.

Residents reported visible pollution and an absence of wildlife in the area last weekend and blamed Virgin’s publicity stunt.

But prior to the marketing tactic, a cabin cruiser, the Earnest Endeavour, sank nearby, causing a small amount of diesel to leak into the river.

A Port of London Authority spokesman said: “There is no connection whatsoever between Virgin’s amphibious vehicle and the pollution.

“What people are seeing is a relatively small amount of diesel that inevitably ends up in the water when a boat sinks.

Fortunately, diesel evaporates quickly so the effects shouldn’t last long.”

A Virgin Media Business spokesman also confirmed there was no link between their stunt and the diesel leak.
