Southwark Council has announced new leadership positions, including the cabinet member for regeneration, planning and transport.
Councillor Mark Williams (above) has been appointed to replace former portfolio holder Fiona Colley, who will become cabinet member for finance, strategy and performance.
Williams was elected as a councillor for the Brunswick Park ward in May 2011.
Councillor Peter John remains leader of the council. He said: "I am really pleased to be able to confirm our new cabinet and their portfolios for the coming term.”
The Labour Party retained its control of the borough, with its total number of seats rising to 48 from 35 in 2010. The Liberal Democrats came in second place with 13 seats. The Conservative Party's representation was reduced from three seats to two.
John said: "The election result gave us a clear mandate from people in the borough to continue with our work of delivering a fairer future for all.
"Southwark faces continued government cuts in the coming years, but we are not prepared to let that restrict our ambition for our borough. The new cabinet is already starting work on our key promises to deliver 11,000 new council homes, making swimming and gym use free for all residents and delivering more quality affordable childcare to help parents and carers to balance work and family life.
"This cabinet has the talent and experience we need to deliver our exciting plans and with them I am confident that we can continue delivering a fairer future for all in Southwark."
"We've already surpassed one degree of global warming," said Kristen Buida, manager of the London Climate Change Partnership.
