Deputy prime minister John Prescott will follow up on his honorary fellowship of the RIBA by giving a "controversial" keynote speech on sustainable communities at the institute.
Prescott was among 18 individuals awarded honorary RIBA fellowships this week for advancing the cause of architecture.

In a short acceptance speech, he said architects and other professions needed to work together to create sustainable communities "developed to the best quality of architecture and design".

Prescott went on to accept RIBA president George Ferguson's invitation "to speak about the tremendous potential of architecture and design to create sustainable communities" and "the skills and ways of working needed".

Although the format and date of the debate have still to be agreed between the RIBA and the Office of the Deputy Prime Minister, Prescott said: "I can guarantee it will be controversial."
