ON THE BOARD: Louise Makin, 60 Chairman, Halma

Smoke detector maker Halma has appointed Dame Louise Makin chairman –making her the 12th woman to hold the job in the FTSE 100.

The mother-of-two replaces Paul Walker at the safety equipment maker in July. 

She spent 15 years as chief executive of healthcare firm BTG and is a non-executive board member at testing company Intertek, where she will step down in June. 

Makin was a non-executive director at Neil Woodford’s Patient Capital Trust but left several months before it was taken over by Schroders.
