Yesterday saw Kingfisher file with the French stock market regulators for the approval of its formal cash offer for the minority shareholding in Castorama. The British group will acquire a casting vote at meetings of the executive bodies of Castorama through its wholly-owned subsidiary Socodi. In the event that the group holds at least 95 per cent of the voting rights, Kingfisher will consider whether to make a public offer for the shares still held by a diversity of shareholders. Castorama shares may perhaps be delisted following such an offer.
