Although talks are still ongoing between NTL and Virgin Mobile, it is understood that if the tie-up is agreed, all NTL's operations will be rebranded Virgin.
Insiders say that the power of the Virgin brand is the key reason for the proposed deal, so the top marketing post would be one of the most important roles within the merged company.
James Kydd is Virgin Mobile's top marketer, while NTL divides its marketing responsibilities across its different business functions.
The merger will create the UK's first quadruple play entertainment giant, offering mobile and fixed-line telephony, broadband and television, enabling it to rival BSkyB and BT.
Virgin and NTL have confirmed the talks, with Virgin adding that it is negotiating with NTL 'for the exclusive use of the Virgin brand' across television, fixed-line and mobile telephony.
The merged company will serve more than 9m customers and is expected to be worth £4.5bn. It may also rival BSkyB by bidding for several of the Premiership's football packages at the end of next season.
