Slaughter and May, Freshfields Bruckhaus Deringer, Shearman & Sterling and Latham & Watkins are among a raft of firms to have won roles on Vodafone's €18.4bn (£16.1bn) purchase of the majority of US cable giant Liberty Global's European assets.

The deal will see Vodafone expand its mobile, cable television and broadband services across the continent with the acquisition of businesses in Germany, Hungary, Romania and the Czech Republic, including Unitymedia, one of Germany's largest cable networks.

Slaughters is advising longstanding client Vodafone, fielding a team led by M&A head Roland Turnill, alongside corporate partner Susannah Macknay and competition partners Claire Jeffs and Kerry O'Connell.

The magic circle firm's team also includes tax partner Steve Edge, finance partner Oliver Storey, employment partner Jonathan Fenn, intellectual property (IP) and IT partner Duncan Blaikie and real estate partner Jane Edwarde.

Freshfields, meanwhile, has taken the lead corporate role for Liberty Global, the parent company of Virgin Media. The firm's team is being led by corporate and M&A partner David Sonter alongside IP/IT partner David Brooks, tax partner Peter Clements, employment partner Alice Greenwell and Brussels competition partner Sascha Schubert.

Slaughters and Freshfields also both advised Vodafone and Liberty respectively in 2016, when the companies agreed to merge their Dutch operations in a deal that saw Vodafone make a €1bn cash payment to Liberty. That deal also handed roles to Allen & Overy (A&O) for Liberty and Dutch firm NautaDutilh for Vodafone.

Freshfields also acted for Liberty Global on its 2014 purchase of a stake in ITV, with Sonter leading the firm's team, while Slaughters took a lead role on Vodafone's 2013 disposal of its 45% stake in US mobile company Verizon Wireless. Turnill played a key role on that deal, assisted by tax partner Edge.

Shearman and Ropes took the lead roles for Liberty Global on its $23.3bn purchase of Virgin Media in 2013, a deal that also handed roles to A&O, Hogan Lovells, Fried Frank Harris Shriver & Jacobson and Milbank Tweed Hadley & McCloy.
