The long-serving Lib Dem lost his Thornbury & Yate seat to Tory Luke Hall.
Hall got 19,924 votes compared to Webb’s 18,429, which was 14% down on the last election.
The Conservative vote was up 4% with UKIP also making significant gains.
MP Steve Webb (pictured) was the longest serving pensions minister with his five-year stint.
His major policy pushes included reform of the state pension and integrating George Osborne’s pensions freedom policy.
Business secretary Vince Cable also lost his seemingly safe Liberal Democrat seat in south-west London.
He lost his Twickenham constituency to Tory Tania Mathias.
