Duchess of Edinburgh 'saddened' by death of woman hit by police escort
A woman hit by a police motorcycle escorting Sophie, the Duchess of Edinburgh, through London has died.
The family of 81-year-old Helen Holland, from Birchanger in Essex, said she fought "for her life for nearly two weeks... but irreversible damage to her brain finally ended the battle".
Buckingham Palace said the duchess was "deeply saddened" and sent her "deepest condolences" to all the family.
The police watchdog is investigating the crash.
Ms Holland had been in London visiting her sister when she was struck at the junction of West Cromwell Road and Warwick Road in Earl's Court on 10 May.
Following the crash, her family said she was in a coma, and on Friday the police said she remained in a critical condition.
Announcing her death, her son, Martin Holland, said his mother had died after "suffering multiple broken bones and massive internal injuries".
Sophie, who is married to the King's youngest brother, will get in touch privately with Ms Holland's family.
She gained the title of Duchess of Edinburgh when her husband Prince Edward took on a new role in March.
Chief Supt Richard Smith, head of the Metropolitan Police's Royalty and Specialist Protection Unit, said the "tragic outcome is being felt by colleagues across the Met" and "thoughts are very much with the woman's family and loved ones".
"Officers know that their actions, both on and off duty, are open to scrutiny and following our referral of the incident, the IOPC launched an independent investigation - we continue to co-operate with and support that inquiry," he said.
The Independent Office for Police Conduct (IOPC), which investigates the most serious incidents involving officers, said its inquiry was "at an early stage".
It issued a witness appeal last week and said it "would still like to hear from anyone who saw or recorded any part of this incident who is yet to speak to us".
The watchdog also said it had been in touch with Ms Holland's family to explain its role and would keep them updated on the investigation.
The duchess has recently returned from a two-day visit to Iraq's capital Baghdad where she met the country's leaders and visited a girls' school to hear from pupils about their education.
