Former BP managing director and current Unilever non-executive director Byron Grote is to become the latest addition to the revamped Tesco board, as it continues to undergo huge changes at the top.

Grote will be joining the board as a non-executive director with effect from 1 May and will step down from his roles on the boards of Unilever plc and Unilever NV at the end of this month. He will replace Gareth Bullock, who will step down this week but continue his role on the board of Tesco bank.

Grote is currently a non-executive Director on the boards of Unilever plc and Unilever NV, Anglo American plc, Standard Chartered plc and Akzo Nobel NV. 

Having served nine years at Unilever, Grote will be stepping down from the Boards of Unilever plc and Unilever NV at the end of April 2015.

He spent nine years at Standard Oil of Ohio prior to it being acquired by BP plc in 1987. From 1988 to 2000 he worked across BP in a variety of commercial, operational and executive roles. He was appointed CEO of BP Chemicals and a Managing Director of BP plc in 2000 and subsequently CFO.

The latest moves continue a period of huge board changes.

Earlier this month Jacqueline Tammenoms Bakker and Liv Garfield stood down as non-executive directors. As well as the arrival of Dave Lewis as chief executive and Alan Stewart as finance director last year, Sir Richard Broadbent has been replaced as chairman by John Allan.

Mikael Ohlsson, the former boss of Ikea, and Richard Cousins, the chief executive of Compass, were appointed as new non-executive directors.

Tesco said Grote would bring “extensive executive and non-executive financial and strategic experience.”
