Berwin Leighton Paisner (BLP), Clifford Chance (CC) and Allen & Overy (A&O) have won roles on Europe’s biggest-ever single property sale – the E1.9bn (£1.5bn) acquisition of Banco Santander’s headquarters in Madrid.

The deal, which completed last month, saw the building, in Boadilla del Monte in Madrid, sold to Propinvest under a sale and leaseback agreement.
