Richard Rogers has been reappointed as the architectural adviser to London mayor Ken Livingstone.
His new token salary of £1 represents a pay rise, since he has headed the architecture and urbanism unit at City Hall for free since 2002.
During the next four years, Rogers - who has just turned 70 and is understood to be stepping back from full-time work with his practice, the Richard Rogers Partnership (RRP) - will advise Livingstone on design issues including plans to rejuvenate 100 public spaces across the capital.
Rogers was first signed up as a paid consultant in 2001, during the mayor's first term, but has since worked without payment.
His appointment provoked controversy because of concerns regarding possible conflicts of interest between his advisory role and his work with RRP.
However, an investigation by the London Assembly's standards committee found there was no evidence of any clash of interests.
