A top London cop will be answering questions and explaining the force's use of stop and search powers during a special webchat on Wednesday.

Commander Tony Eastaugh will host the chat between noon and 1pm, giving Londoners the opportunity to ask questions about how officers are using these powers and how the service is setting out to improve its approach, as announced by Metropolitan Police Commissioner Bernard Hogan-Howe.
