The partnership was set up under London mayor Ken Livingstone in 2001 and comprises local authorities, universities, public transport executives, private sector businesses and the Chamber of Commerce.
Plans to extend the current tram link – which runs from Wimbledon to Beckenham via Croydon – were drawn up after a study commissioned by the partnership found the tram had brought substantial economic and regeneration benefits to the areas in which it already operates.
The successful agency will be expected to use the results of the study, which point to a fall in unemployment and a rise in local business development in these areas, to convince regional and national government to back the partnership’s plans.
‘The Mayor is investing heavily in public transport,’ said SLP director Christine Seaman.
‘We want to appoint an agency that will put our partnership at the forefront of all proposals,’ she added.
Four agencies have been shortlisted to handle the account, with the final decision due to be made later this month.
