What were the number of different street markets running in London for each year since 2016? Please provide a breakdown by borough.

Mapping London’s street markets was identified as a priority by the markets sector when I launched my Street and Covered Markets Programme in 2017. Just over 280 markets were mapped across London through the street market mapping tool. The tool allows users to sift through London’s markets by borough, market type and opening times. We do not hold any other data regarding street markets beyond what is available on the street markets mapping tool. Additional data on street markets is however held at a borough level by Local Authorities.
