"I'm really pleased to be taking over from Steph who has done a tremendous job over the last two years, leading the borough operational command unit (BOCU) through some challenging times and I know she is immensely proud of what our officers and staff have achieved.
"Bromley has an excellent reputation for working in partnership with the community and statutory partners and I'm looking forward to leading the BOCU from the 17th of March."
