Southwark interim head of comms Paul Masterman said: ‘We will position the council as a thought leader in the debate about the future of social care provision and funding.’
He added: 'We are going to challenge the government’s use of the Relative Needs Formula.'
The Relative Needs Formula is used to calculate how much funding each council area is allocated for a particular requirement.
Southwark is arguing that the grant received from the Government undervalues the social care demands on the council, specifically from older and disabled people in the borough.
Southwark will aim to influence ministers and civil servants to change the formula that will be used in the next spending round.
