The report suggests the move is the precursor to a dismantling of the company which could see the UK arm sold to Molson Coors.
Such a move would see Cobra added to a growing premium beer portfolio for the US-owned brewer, including Kasteel Cru, Blue Moon and Sol.
Cobra declined to comment on the story early this morning.
McKeon joined Cobra less than two years ago from his post as managing director of Beam Global Spirits & Wine UK.
Last November Cobra founder, chairman and majority shareholder Lord Bilimoria appointed investment bank Rothschild to advise on a what the company described as a “strategic business partnership or sale to achieve the full potential of the business”, after talks with Diageo about a possible 30% acquisition of the whole business stalled on the asking price.
High marketing costs have left Cobra with regular annual losses, despite rapidly-growing sales figures in the UK.
