‘Lounge suit’ is normally a reliable signifier of supine gentility. But there it was on the invitation to Richard Rogers’s 80th birthday retrospective. Can this be the same architect once praised by a president of RIBA for his admirable ‘sod you’ approach to the public?

The same man the Parisians sniffily called an ‘English hippie’ when working on the Centre Pompidou? Surely not the architect who had to buy a cheap suit and borrow a tie to visit his new client, Lloyd’s of London?

And there he was at the head of the receiving line.
