BRUSSELS- EU antitrust regulators are unlikely to demand more concessions from insurance broker Aon over its $30 billion bid for Willis Towers Watson and are expected to give conditional clearance to the deal, people familiar with the matter said.

Aon, which clinched the deal a year ago to create the world's largest insurance broker ahead of Marsh & McLennan Companies Inc, offered concessions to the European Commission earlier this month.

The package includes a wide swathe of Willis assets.
