Co-host Jeremy Clarkson tweeted that it was the "most frightening" accident he had ever seen but said Hammond, who fractured a knee, was "mostly OK".

The show's statement said Hammond had been involved in a "serious crash" after completing the Hemberg Hill Climb in Switzerland, where a race takes place on Sunday.

He had been driving a "Rimac Concept One, an electric super car built in Croatia, during filming for "The Grand Tour Season 2" on Amazon Prime, but very fortunately suffered no serious injury".

Hammond was "conscious and talking" after the crash, , and had been flown to hospital in St Gallen "to be checked over", the show said.
