Tomkins (pictured) has a 17-year career in the City. She is a qualified chartered accountant and was head of equities at Fairfax I.S. before leaving in 2012.

She has since held a number of non-exec positions including non-executive director and chair of the audit committees of Hotel Chocolat Group and Cloudcall Group. 

At System1 she will chair the company’s audit committee and sit on the group’s remuneration committee.

System1 recently announced disappointing full year results for 2018, with revenue falling 18% and pre-tax profits down 68%.

Its current chairman, Ken Ford, is standing down to be replaced by Graham Blashill, who has been a non-exec since 2012.
