Aon has redefined two senior roles as it looks to strengthen its SME/mid-market leadership team and growth capability.

Kevan Johnston, currently Chief Commercial Officer, will become MD Commercial, while Scott Willmot’s role as Chief Growth Officer will be expanded to incorporate Mr Johnston’s previous responsibilities.

Incoming CEO James Baum says the appointments will build on gains made in the SME/mid-market sector. Both appointments are effective from the end of the second quarter.
