(Reuters) - Vodafone Group Plc (>> Vodafone Group plc) is in talks to acquire Spain's main cable operator Grupo Corporativo ONO SA , which could derail ONO's plans for an initial public offering, Bloomberg news reported, citing sources.

A deal could be announced in the next few weeks, Bloomberg quoted one of the sources as saying.

Vodafone and ONO could not be reached for a comment outside of regular working hours.

Sources told Reuters in December that Ono, once listed, would likely be a takeover target for bigger competitors Vodafone (>> Vodafone Group plc) and Orange (>> ORANGE SA), which are trying to capture a larger share of the Spanish market to make headway against former monopoly Telefonica (>> Telefonica SA).
