A former nurse who trained at West Middlesex Hospital has become Hounslow's first mayor to live outside the borough.
Genevieve Hibbs, who has represented the Independent Community Group (ICG) in Isleworth since 2002, was elected on Tuesday evening.
She replaces Lib Dem councillor Andy Morgan-Watts, who attended 550 events over the last year and raised thousands of pounds for his three charities.
Cllr Hibbs spent 22 years in Isleworth but sold her home the day after being elected in 2002 and has since lived in Hayes.
The 73-year-old, who has never married, nominated Syon ward councillor Shirley Fisher as her deputy.
