46-year-old Henry and 27-year-old Smallman were attacked and stabbed to death in June last year after attending a celebration at Wembley’s Fryent Country Park. Their bodies were found the following day by Smallman’s boyfriend, the day after they had been reported missing to the police.

Earlier this week, the Metropolitan Police announced they would formally apologise to the family for the way Henry and Smallman’s case was handled, after an Independent Office for Police Conduct (IOPC) report found that the police’s response was “below the standard that it should have been”.

Responding to the proposed apology in an exclusive interview with Channel 4 News on Tuesday, the sisters’ mother Mina Smallman said the “time for apologies is long gone,” and revealed how the police failed to take her daughter’s disappearances “seriously”.
