It is still a case of "wait and see" for the proposed extension of the East London Line to West Croydon, South Norwood and Crystal Palace.

The extension is seen as a boost to both south and east London by linking them on the Tube network.

It will also play a big part in London's 2012 Olympic bid.

Chancellor Gordon Brown made no mention of the ELL extension project in his spending review speech on Monday but did give the Department for Transport (DfT) a £1.7billion transport reform package to be spent in 2005/06 and 2006/07.

A spokesman for Mayor of London Ken Livingstone said of Mr Brown's review: "This was a fairly general announcement and it is down to Transport for London to see where the funding will go.

"It is good to look forward but the mayor will continue to lobby for the East London extension. It is a case of wait and see."

Despite delays and financial setbacks mayor of London Ken Livingstone revealed his vision of transport links in London by the year 2016.

The new map includes all the planned major transport projects including the East London Line extension and four extra Croydon Tramlink routes, Purley, Crystal Palace, Tooting and Streatham.

Research carried out on behalf of the mayor has projected that London's population will grow from 7.2 million to 8.1 million by 2016.

Mr Livingstone said: "This map represents the future of London's transport system.

"It shows what we need to do to ensure our city's future success.

"This is a transport system which will cope with London's population in 2016."

Transport Minister, Alistair Darling, is due to announce tomorrow (Thursday) the content of the DfT spending review.
