Simmons & Simmons has won KPMG Consulting as a new client ahead of Allen & Overy (A&O) after acting on its £186m acquisition of Andersen Worldwide Business Consulting.

A&O in June this year acted for KPMG Consulting on the completion of its split with its big four accounting parent KPMG, which saw the £440m acquisition of local arms in Germany, Switzerland and Austria.
