Norton Rose has advised SG Hambros – part of Societe Generale’s (SocGen’s) private banking unit – on its eye-catching acquisition of ABN Amro’s E1bn (£699m) London-based private banking business.

The top 10 City law firm acted opposite magic circle giant Freshfields Bruckhaus Deringer on the private buy-out, which was for an undisclosed sum. The business is known to have at least E1bn of assets under management. Norton Rose, which is also on SocGen’s global panel, was handed the mandate six weeks ago.
