Slaughter and May, Allen & Overy (A&O) and Clifford Chance (CC) have secured roles on the £2.5bn sale of Durex manufacturer SSL to cleaning products group Reckitt Benckiser.

Slaughters advised Reckitt Benckiser with a team including corporate partner Jeffrey Twentyman and associates Anna Lee and Dan Won. The deal team included finance partners Andrew Balfour and Andrew McClean, competition partner Claire Jeffs and pensions and employment partner Eddie Codrington.

A&O corporate partner Richard Hough led the firm's team for SSL and while CC finance partner Nicola Wherity advised HSBC on the £1.25bn loan facility being used to finance the offer. Deutsche Bank also provided financial advice for Reckitt Benckiser.

Hough commented: "The offer is at a significant premium to the SSL share price and represents a four-fold increase over the past five years. This is down to the management team's vision and ability to build a global consumer brand business and generate exceptional shareholder value."

Reckitt Benckiser said that the deal would expand its presence in China and Japan.

The deal comes in the same week that Slaughters secured a role on another multibillion-pound mandate after being instructed to advise engineering company Tomkins on a bid £2.9bn for the company.

The bidding consortium, which comprises private equity group Onex Corporation and the Canada Pension Plan Investment Board, is being advised by Freshfields Bruckhaus Deringer.
