Hemel Hempstead Dunn first stood for Parliament at the
1923 general election when he was selected as Liberal candidate for the
Hertfordshire seat of
Hemel Hempstead. In a good year for the Liberal Party, reunited after the splits of the
Lloyd George and
Asquith rivalries, Dunn defeated the sitting
Conservative MP,
J C C Davidson, in a nail-bitingly close straight fight by the margin of 17 votes. At the
1924 general election, the
Tory Party had recovered its position and with
Labour also standing a candidate, Davidson regained his seat with a majority of nearly 5,000. ===
Faversham by-election=== Dunn got a chance to re-enter the
House of Commons in January 1928 when he was selected as Liberal candidate in a by-election at
Faversham in
Kent, following the death of the sitting Conservative MP, Sir Granville Wheler. In a four cornered contest with Conservative, Labour and Independent Conservative opponents, Dunn came third with 18.6% of the poll.
Chichester Dunn tried once more for Parliament, this time at
Chichester in
West Sussex at the
1929 general election. However, in a straight fight with the Tories the sitting MP,
