The body must clear the Olympic site for development by July 2007 - which is likely to involve controversial compulsory purchase orders for businesses located in the area.
‘Our role is to clear the site; then after the 2012 Games we are in charge of the legacy of the event,' press officer Andreas Christophorou told PRWeek.
Two-year agency contracts will cover PR, marketing, brand strategy, internal comms and sponsorship.
Briefs will include communicating with specific groups - such as women, the disabled, faith groups, ‘transgender people', and ethnic minorities.
Overseeing the roster is brand marketing manager Clare Sydney. The existing list boasts 15 agencies, which the LDA declined to name.
Although primarily for the use of the LDA, the roster will also be used by bodies including the London Fire and Emergency Planning Authority, Transport for London, The Metropolitan Police Authority, and the London Climate Change Agency.
Plans to build a ‘mega-mosque' close to the 2012 site have attracted opposition from various groups.
