Mrs. Berridge suffered from heart problems in later life and while apparently in good health and spirits was taken ill suddenly at a dance in Kensington and died in a few minutes in February 1909.

He was some time Chairman of the Law and Parliamentary Committee of the Board of Works for the St Giles District in London[5] and he wanted a full-time career in politics.

[6] In the summer of 1902 there were rumours of a possible vacancy in the constituency of Warwick and Leamington when the sitting Liberal Unionist member Alfred Lyttelton was tipped for an appointment to be a Judge or Governor of a British Colony.

[9] Benefitting from the surge in support for the Liberal Party at the general election, Berridge won Warwick and Leamington with a majority of 209 votes, removing Lyttelton from the House of Commons,[10] at least for a few weeks until he was returned unopposed at a by-election for the seat of St George's, Hanover Square in Westminster.

Berridge remained MP for Warwick and Leamington for four years until the general election of January 1910 when he was defeated by the Conservative Ernest Pollock.
