It had been forced to release a statement confirming it was looking into a move yesterday

Aon has pulled out of exploring a deal to buy fellow broker Willis Towers Watson, it confirmed in a statement.

”Consistent with Aon’s stated focus on return on invested capital the firm regularly evaluates a variety of potential opportunities within and adjacent to its industry. Aon had considered such a possibility with regard to Willis Towers Watson.

”News of that consideration subsequently became public and Aon was required to issue a statement because Willis Towers Watson is an Irish company and is subject to Irish regulatory requirements.

”As a result of media speculation, those regulations required Aon to make the disclosure at a very early stage in the consideration of a potential all-share business combination. Aon today confirms that it does not intend to pursue this business combination,” it said in a statement.
