CRH, the Irish construction materials group, gave up its bid to secure three seats on the board of Spanish cement company Corporacion Uniland yesterday, claiming that it did not wish to collaborate with the current board. At a shareholders’ AGM, originally scheduled to discuss CRH’s request, the Irish group proposed to shareholders that action be taken against the board for five reasons, chief among them the fact that the board was holding talks to sell the 73.7 per cent stake in Uniland not controlled by CRH.
