Linklaters and legal and wealth services firm Maitland have taken lead roles on a $5.1bn (£3.2bn) deal that will see the Oppenheimer family sell its stake in diamond company De Beers.

The deal, announced last week (4 November), will see mining company Anglo American buy the Oppenheimer family’s 40% stake in De Beers – increasing its interest in the world’s leading diamond company to up to 85%.
