According to sources the 60-year-old, officially known as Lord Browne of Madingley, left back in May having ‘not really ever started’ his role as a non-executive director.
Browne was appointed to the board in September last year (AJ online 29.09.07) after stepping down as head of the international oil company back following a flurry of tabloid tales about his private life.
The president of The Royal Academy of Engineering and a trustee of both the British Museum and the Tate, Browne blamed a hectic schedule for his departure.
A spokesman for the practice said: ‘[Lord Browne] found that he was busier than expected and therefore due to pressure of other commitments has resigned.’
Browne’s arrival was hailed as a ‘real coup’ by Foster + Partners when he became the first senior non-executive to be appointed since a private equity company took a minority share in the practice.
