The BBC has cancelled a Top Gear Live event that was scheduled in Norway next week with Jeremy Clarkson as its star.
In another indication the corporation may be about to sack the controversial presenter, a spokesman apologised to fans and said the four shows would need to be rescheduled.
Only last week, the BBC insisted the events would go ahead, despite Clarkson's suspension for allegedly punching a producer in a row over hot food. At the time, insiders said Top Gear Live's producers did not want to disappoint the 20,000 fans who had booked tickets. But the last-minute cancellation suggests a change of heart and that Clarkson's days at the BBC may be numbered.
A Top Gear Live insider insisted the decision to cancel the show had been taken because of the obvious uncertainty around Clarkson's immediate future, and that producers had been given no indication of whether he would be sacked.
His fate is expected to be announced this week after he gave evidence to an inquiry headed by Ken MacQuarrie, head of BBC Scotland.
Clarkson, who is paid a seven-figure salary to present Top Gear, has a separate seven-figure contract with BBC Worldwide to host the Top Gear Live events around the world.
And while his contract with the BBC is due to expire at the end of this month, his BBC Worldwide contract runs until September, with live shows booked for Australia, South Africa and Britain.
The presenter was suspended by the BBC on March 10. Clarkson is alleged to have punched producer Oisin Tymon after being told he could not have steak and chips for dinner because the hotel they were staying in had stopped serving hot food.
