Bookmakers offering virtual odds on this year's Royal Gold Medallist (to be announced on Wednesday week at the next RIBA council session) won't get much comfort from an examination of this year's judges, chaired as usual by the RIBA president. Since they include a range of architects and critical positions from Lord Foster to Mohsen Mostafavi it is difficult to imagine how consensus might be reached.Were Astragal to have a flutter, however, three joint favourites have emerged from the throng. One would be Peter Cook, representing the Archigram group - arguably the only truly influential British contribution to 20th century architecture (sort of including High-Tech). Representing European Modernism is Rafael Moneo, surely bound to win one year. Finally, and bound to draw support from the High-Tech and engineering lobby, there is Frei Otto, patron saint of tensile structures.Take your pick.
