In 1990 he became Chairman of his ward and subsequently Chairman of the Cities of London and Westminster Conservative Association in 1992. Patrick has been President of the Association since 1994 in addition to running the Two Cities Luncheon. The Luncheon has had all the Party leaders of the last 50 years as Guests of Honour and has raise very large sums for the Party – in excess of £100,000 some years.

During this period the Association recruited between 350-400 new members each year.
