The family of an elderly woman who collided with a convoy escorting the Duke and Duchess of Cambridge has revealed the extent of her injuries.
Irene Mayor, 83, has suffered a broken pelvis, broken arms, a broken leg and bad head wounds after she was hit by the motorbike on Monday.
The woman's sister Joyce Shore told the Daily Mail that she fears Irene "may not get through this".
She told the publication: "Irene may not get through this. She is just an ordinary lady who minds her own business and then this happens. I do like the royals, but the way my sister's life has been endangered is completely unacceptable. The police outriders have to slow down.
"My sister is lying in a hospital bed and she could have been killed. She could so easily have been killed. She is in intensive care and she will not be released."
Ms Mayor's brother also praised the Duke and Duchess of Cambridge for reaching out to the family.
Meanwhile, Louise Rawlinson helped attend to Ms Mayor before paramedics arrived.
She told the Daily Mail that she was moving furniture out of her shop when a passing police bike made a noise.
Ms Rawlinson said she turned around to see the pensioner on the floor with shopping bags around her.
I do like the royals, but the way my sister's life has been endangered is completely unacceptable.
She said Ms Mayor had an injury to the back of her head which was bleeding heavily, which she held and treated.
Ms Rawlinson said she overheard paramedics at the scene say that Ms Mayor had been clipped by a wing mirror.
It comes after the Independent Office for Police Conduct (IOPC), which is investigating the accident, said: "The woman, in her 80s, suffered serious injuries and was taken to a London hospital where she remains in a serious but stable condition.
"In line with procedure, the Metropolitan Police Service referred the collision to the IOPC.
"Our staff attended the scene of the incident and after careful consideration, we have launched an independent investigation.
"The investigation is in its very early stages and the officer involved is assisting our enquiries as a witness.
"Our immediate thoughts are with the injured woman and her family and those affected by the incident."
Kensington Palace said: "The Duke and Duchess of Cambridge were deeply concerned and saddened to hear about the accident on Monday afternoon.
"Their Royal Highnesses have sent their very best wishes to Irene and her family and will stay in touch throughout every stage of her recovery."
