The full march will be ten miles, from the park where Nicole and Bibaa were tragically murdered to the doors of New Scotland Yard, which the WEP say lays “ the responsibility for racist, misogynist policing firmly at their doors.”

A report into the handling of Henry and Smallman’s murders found failures by an inspector to “properly progress” missing persons enquiries for Smallman or Henry, meaning resources were not deployed until mid-morning on 7 June.

It stated that the Met was wrong not to progress the case sooner – and that doing so could have saved the family from discovering the sisters’ bodies after they took it upon themselves to launch a search party.

Two Metropolitan police officers were later jailed for two years and nine months each after pleading guilty to misconduct in a public office. PC Deniz Jaffer, 47, and PC Jamie Lewis, 33, sent photos they took of the sisters’ bodies to other officers via WhatsApp, describing the pair as “dead birds”

The sisters’ mother, Mina Smallman, has maintained that there were racist elements to the police’s failings – despite the official Independent Office for Police Conduct (IOPC) report into the investigation saying there was no suggestion “racial bias” played any part.

The Metropolitan Police later announced they would formally apologise to the family for their response to the two women’s disappearance.
