Lambeth council leader is to quit the post for a job as director of the Greater London Authority’s new violence reduction unit.
She has led Lambeth council through a difficult six years and was a councillor for 17 years.
Peck said: “Lambeth is a fantastic borough with hugely committed, inspirational and engaged communities.
“It has been a real privilege to be the leader of Lambeth council since 2012, and a councillor for Thornton ward since 2001.
“During my time as leader there have been huge challenges to overcome, as well as huge achievements recorded.
“My fellow councillors, Lambeth council staff and our partners in the borough have worked together throughout to deliver for our residents. There is much that I am proud of.
“One of those challenges has been tackling youth violence, where Lambeth has taken a leading role.
“I have also been involved in Greater London Authority’s new violence reduction unit since its inception in 2018 as part of my role as deputy chair of London councils and executive member for crime and public protection.
“When the opportunity arose to lead the unit tackling this issue at a London-wide level, I felt this was an opportunity I must take.”
Lambeth council said it was the first authority in England to develop its own public health response to violence, following the model successfully developed in Glasgow.
The London-wide Violence Reduction Unit plans to divert people away from violence by making interventions at an early age and providing young Londoners with better, positive life opportunities.
