Insurance broking giant WTW has been dusting itself off after US competition authorities pulled the rug from under an attempted $30bn acquisition by Aon.

Shortly after the deal fell through a new chief executive, Charles Hess, was appointed. Then, under a corporate rebranding, the old Willis Towers Watson name was dropped for the more succinct WTW.

WTW is one of the leading marine insurance brokers covering all the main lines including protection and indemnity, cargo, hull, war risk and marine liability.
