Before joining City Hall, Johnson Situ was a senior Labour Councillor in Peckham for close to eight years. His Southwark Council Cabinet portfolio included the council’s response to the Climate Emergency, and he led the council’s work to bring the community together through Southwark Stands Together. 

Before working in politics, he worked in the international development sector for various organisations, including Comic Relief, the Disasters Emergency Committee, and Room to Read.
