The organisers have demanded that the capital’s streets be a safe place for women.
The vigil will begin at 6pm on Saturday at the bandstand in Clapham Common. Attendees are asked to wear a mask and practice social distancing.
In a description for the event, the organisers said “We believe that streets should be safe for women, regardless of what you wear, where you live or what time of day or night it is.
“We shouldn’t have to wear bright colours when we walk home and clutch our keys in our fists to feel safe.
“It’s wrong that the response to violence against women requires women to behave differently. In Clapham, police told women not to go out at night this week. Women are not the problem.”
It comes after a vigil was held for Ms Everard on Wednesday outside Scotland Yard, where police gave an update on the investigation.
Late on Tuesday, the Met Police said a serving officer from the force had been arrested as part of the investigation.
On Wednesday, the force said he had been initially arrested on suspicion of kidnap, and later murder, as well as a separate allegation of indecent exposure.
A woman in her 30s was also arrested on suspicion of assisting an offender.
On Wednesday evening police recovered human remains while searching for Sarah in an area of woodland in Ashford in Kent.
“We have found very sadly what appears to be human remains,” Met Police Commissioner Dame Cressida Dick said.
“At this early stage we are not able to confirm any identity and that may take us some considerable time”, she added.
“Specialist officers have been with Sarah’s family to update them on the investigation and continue to give them the best support possible.”
