Shareholders at French supermarket retailer Carrefour, have been pressing for board changes de to frustrations with the group’s continued underperformance in its core French market.

Last month the group announced the departure of its third board director in less than four years, and now Daniel Bernard is said to be under pressure from shareholders who are unhappy with his management of the company, according to a report in today’s Financial Times.

Luc Vandervelde, the former chairman of Marks & Spencer, is expected to be appointed as the non-executive chairman of the company within a month.

Vandervelde has been on the Carrefour board since 2003 as the representative of the Halley family, which owns 11.5% of the company’s shares.
