Labour peer Lord Rogers' modernist design for the Chelsea Barracks site in London was dropped last week after Charles wrote to the developers, the Quatari royal family. The 61-year-old royal who has always taken a keen interest in architecture and famously once described a proposed extension to the National Gallery as a "monstrous carbuncle", called the plans "unsuitable" and suggested a more classical design.
Lord Rogers said "Are we going to have royalty dictating to us modern art… their taste in music or their belief in medicine?... No because they're not experts any of those fields."
The designer called for an expert panel of constitutional experts to enquire into the political powers of the Prince. An Oxford professor of politics and government spoke up his defence, however, saying the Prince can make whatever contribution he wishes to public debate "as long as he is not partisan".
The academic added: "The fact that one does not agree with what he says does not make it unconstitutional."
