London 2012 might be a fading memory but ongoing membership of a committee promoting its legacy could be set to cost the council £10,000 annually.

Councillors are expected to vote in favour of joining the new Growth Boroughs Joint Committee, envisioned to “foster and develop co-operative joint working” and “secure local benefits and a sustainable legacy”, at tonight’s cabinet meeting.

In return, they would be required to make a contribution to its yearly £60,000 budget.

The five original host boroughs for the London 2012 Olympic and Paralympic Games - Hackney, Greenwich, Newham, Tower Hamlets and Waltham Forest - originally formed an agreement to work together in 2006, before forming a joint committee three years later.

In 2011, the host boroughs agreed to admit Barking and Dagenham as the sixth member.

Now there are plans afoot to disband the existing committee before establishing the six Growth Boroughs committee, complete with a revised terms of reference to “reflect the scope of the tasks ahead”.

A report prepared in advance of tonight’s meeting stated that its aims are “consonent with the Council’s priority of growing the borough”.

It notes that the likely financial contributions towards the committee’s budget are in line with what was previously required and “is within existing budgets”.

Withdrawal and non-participation in the new group is “not seen as an acceptable option” as involvement is regarded as a good opportunity of “advancing and fulfilling” objectives to deliver homes and jobs and enhance the borough’s image to attract investment and business growth.

A spokesman for Barking and Dagenham refused to discuss the benefits of being part of the legacy committee until after the cabinet meeting has taken place.

Former council leader Liam Smith is a member of the existing joint committee, which at the moment consists of two members from each host borough and is chaired by the Mayor Of Newham, Sir Robin Wales.

Despite attempts to promote the Olympic legacy, Barking and Dagenham was named as the second least active borough in the whole of England in the results of a survey released last week.

It comes less than a year after the borough’s sports participation figures were found to be the lowest in the capital.
