Top Gear's Matt LeBlanc gatecrashes London 'wedding'

Top Gear host Matt LeBlanc gatecrashed a "wedding" at St Paul's Cathedral while touring round the capital during filming.

He was joined by professional rally driver Ken Block as he spun around the city in a Ford Mustang.

The "wedding party", staged by actors outside the London landmark for the show, got a wave as they drove through the City of London.

The duo in Block's 845bhp 4WD Hoonicorn Mustang took a selfie on Tower Bridge.

At first it was thought it was a real wedding, but it later became clear the event had been staged for the programme.

Matt LeBlanc also tweeted a picture of himself from Canary Wharf saying: "Canary wharf is nice."

Paul Bradbury, head of retail at West Bromwich Albion Football Club, was in the capital with his wife for the weekend for a football match and caught the action at St Paul's Cathedral.

Mr Bradbury, from Newcastle-under-Lyme, Staffordshire, said: "It was very very loud and entertaining but everyone seemed to enjoy it.

"Matt LeBlanc walked down and had a quick look of the route before he jumped in the car.

"The car seemed to stall for a couple of minutes but they got going again and made a couple of takes with the wedding party on the steps."

The new series of BBC Two show is due to start in May.
