Stella McCartney is "very apologetic" after failing to give her details to a cab driver whose car she hit with her Mini Cooper.
The 45-year-old fashion designer was driving in heavy traffic through Hammersmith, west London, when she pranged Arash Nabezadeh from behind.
Stella – who is the daughter of music legend Sir Paul McCartney – "thought she had done the right thing" when she allowed Arash to take her license plate details but refused to give any further insurance details to the driver.
In video footage filmed by Arash and obtained by The Sun newspaper, Stella said: "Just do whatever you need to do. Take the number of my licence plate. Do whatever you need to do, no problem."
When Stella drove off, Arash followed her to a nearby school where he claims she again refused to hand over her details, but eventually took his phone number.
A day after the incident, Stella’s husband Alasdhair Willis – with whom she shares four children, Miller, 11, Bailey, 10, Beckett, nine, and Reiley, six – called Arash and passed on the contact details of their insurance broker and a policy number.
A spokesman for the designer confirmed she "accepts liability" for the incident, and said her actions came as she believed Arash would be able to make an insurance claim from the license plate alone.
The spokesman said: "Ms. McCartney has never been in this type of incident before.
"Although she and the taxi driver did not swap full details, Ms. McCartney thought an insurance claim could be made from the licence plate number she was happy to provide and knew the driver had a note of.
"She thought she had done the right thing.
"When the driver, with two passengers, started filming her she felt intimidated — particularly when she realised they had followed her to the kids’ school, still filming her.
"She accepts liability for the incident and is very apologetic for any issues that have arisen."
