Kingfisher, which also owns B&Q and Comet, wants to sell or float the electricals arm and focus on DIY. Castorama chief Jean-Hugues Loyez said Kingfisher's offer of e67 (£43.40) a share is too low. He voiced his objections in an 'open letter' in French newspapers Les Echoes and La Tribune. Ultimately, investment bank Rothschild, which has been appointed adjudicator, will decide if the price is fair.
