LONDON, Nov 18 (Reuters) - Liberty Global (LBTYA.O) Chief Executive Mike Fries said the opportunity to sell wholesale access to its British broadband network was "ripe for the picking", but the company"s Virgin Media-O2 joint venture was in no rush to announce a deal. "The wholesale opportunity is ripe for the picking," Fries told the Morgan Stanley European Technology, Media and Telecoms conference on Thursday. "If there"s anybody on this call that thinks that BT Openreach isn"t going to have competition for wholesale: there"s just zero probability of that." He said emerging fibre broadband network builders in Britain would be hit by the roll-out plans of Virgin Media-O2 - jointly owned by Liberty Global and Telefonica - and BT (BT.L).ink the window is slowly closing for many of these alt-nets," he said. "There"s not enough wholesale customers to support their network construction. And they only have a fraction of the funding they actually need."
