Clifford Chance (CC) and Allen & Overy (A&O) have scored lead roles on the near-£1bn purchase of a 60% stake in UK retailer B&M Bargains by US private equity group Clayton Dubilier & Rice (CD&R).

CD&R has bought the majority stake in the Liverpool-based discount chain from Manchester businessmen Simon, Bobby and Robin Arora, who have built up the business since acquiring it in 2005. The deal, which is reportedly worth £965m, is expected to close early in 2013.
