The sale comes on the heels of Aon and Willis Towers Watson calling off its proposed merger and ending litigation with the U.S. Department of Justice in July. The merger, which was first announced in March 2020 and received shareholder approval in August 2020, was challenged in June, with the DOJ asserting the deal could eliminate competition, raise prices and hamper innovation for U.S. businesses, employers and unions that use the two consultancies’ services.
