The grieving son of an 81-year-old woman who died after being hit by Sophie Wessex's motorcade has demanded an apology from police.
Helen Holland was seriously injured when she was struck by a police motorbike at Earl's Court in west London earlier this month, with an eyewitness claiming at the time that she was "thrown 40 feet across the road".
Announcing her death, her son Martin told the BBC that she fought "for her life for nearly two weeks... but irreversible damage to her brain finally ended the battle".
