South Thames College and Merton College could join forces in a bid to create one single, stronger institution.

A proposal for the merger will be put forward to the Learning and Skills Council (LSC) later this year and, if supported by the LSC, a public consultation will be launched on the plans.

The colleges said the move was a response to the "unprecedented changes" taking place in education, such as new diplomas and greater involvement with businesses and with training employees.

They added that the new college would build on the courses currently offered at the current premises, and there were no plans to close any buildings as a result.

Sue Rimmer, principal of South Thames College, said: "We intend to become the leading provider of educational opportunities in the region and look forward to working together."

Merton College principal Sally McEnhill added that the merger would provide more choice for young people and adult learners.

She said: "Together we can grow a truly excellent reputation as a further education and sixth form college for Merton, Wandsworth and South London."

South Thames College teaches more than 21,000 students at five sites across Wandsworth, with the Putney site earmarked for closure once work is complete on a £68.5m redevelopment at the Wandsworth campus.

Merton College caters for around 6,800 students, and has recently opened £30m worth of facilities in London Road, Morden.

Councillor Kathy Tracey, Wandsworth executive for children and young people's services, said the proposal appeared to be a good move as it would stop the colleges competing, particularly for student work placements.

She added: "As Merton College is on the edge of inner London, it's difficult recruiting high-calibre staff as they don't get London weighting. The merger could mean they are upgraded to London weighting. I think it's a pragmatic amalgamation."
