Sir Steven John Webb PC (born 18 July 1965) is a British pensions commentator who was previously Liberal Democrat Member of Parliament (MP) for Northavon from 1997 to 2010 and for Thornbury and Yate from 2010 to 2015.

In the first reshuffle after the leadership election, he was appointed Liberal Democrat Environment, Energy, Food and Rural Affairs spokesman.

Following Gordon Brown's reshuffle in October 2008, he shadowed Ed Miliband in the newly formed Department for Energy and Climate Change.

On 8 January 2009 Nick Clegg announced his "General Election Team" and an "economic recovery group" with Webb appointed as Work and Pensions spokesman.

[3] Given his increasing profile and popularity within the party due to his role as the manifesto chair, he was seen as a probable candidate for the social liberal grouping's vote in the future leadership election.

Despite this, on 18 October, Webb announced he was not running, and would be backing Nick Clegg for leader, who was ultimately the successful candidate.

[12] In August 2015, it was announced Webb was becoming director of policy and external communications at the financial services mutual Royal London.

[14] A freedom of information inquiry tabled by Webb in 2020 revealed that a large number of women were being paid state pensions below the expected rate.
