Prince William and Kate Middleton were “aggressively” pursued in their car by the paparazzi last night, Clarence House said today.
Second in line to the throne William was left concerned by the threatening behaviours, his spokesman, Paddy Harverson, said.
Mr Harverson added that the events seemed incomprehensible at this particular time.
The incident happened in a week which saw the start of the inquest into the death of William’s mother, Diana, Princess of Wales, whose car crashed in Paris in 1997 as she was being followed by photographers.
The couple, who have rekindled their relationship after splitting up earlier this year, were leaving London's Boujis nightclub in the early hours of the morning.
Mr Harverson said: “Prince William was concerned by the threatening behaviour of the paparazzi in London last night.
“Having already been photographed leaving the club, he and Kate Middleton were then pursued in his car by photographers on motorcycles, in vehicles and on foot.
“The aggressive pursuit was potentially dangerous and worrying for them.
“It seems incomprehensible, particularly at this time, that this behaviour is still going on.”
