The ruling Dominica Labour Party (DLP) gained a landslide victory in the general elections held on 24 March 1975.  The DLP won 16 seats in the 21-seat house of assembly.  Candidates from Dominica’s three opposition parties and independents, despite winning approximately 45% of the popular vote, fared badly in voting.  The principal opposition party, the Dominica Freedom Party (DFP), won only three seats while the remaining two seats were won by independents.  The Caribbean Federal Party (CFP) and the Progressive Labour Party (PLP) failed to win any seats.  Voter turnout in the election was high at 79.0% and the elections were conducted in a fair and honest manner.

The only two candidates running out of eight DLP members of the house elected in 1970, Premier John and Education Minister H.L. Christian, retained their seats.  Among the more prominent newly elected DLP members of the house were former Speaker of the House Eustace H. Francis, Michael Douglas, and DLP Vice President J. Oliver Seraphine.

Opposition leader in the house Anthony Moise and newcomer A. Anthony Casimir won seats as expected, but former member of the house R.  Stanley Fadelle was defeated in an upset victory by DLP candidate Luke Cornette.  Unofficial leader of the DFP Mary Eugenia Charles won a surprise victory over her DLP opponent by a large margin of 200 votes.

The Progressive Labour Party (PLP) failed to win any seats despite having been heavily favoured to win at least two of the eight seats it was contesting.  Both PLP chairman Jenner B.M.  Armour and Carib Indian Chief Macclem C. Frederick lost their races to their respective DLP opponents, Randolph Bannis and Lawrence Darroux.  Darroux is the first Carib Indian ever elected to the Dominican House of Assembly.  PLP founder Ronald O.P. Armour, former Leblanc protégé and Deputy Premier, lost his deposit in the race for the Newtown seat won by the DLP's Francis.

The Caribbean Federal Party likewise failed to win a seat.  Independents also fared poorly as only two of the eleven running won seats.  Pattison "Pat" A.S. Stevens and Conrad W. Cyrus were elected to the house as expected, but other independents regarded as strong candidates, for example, alleged MND member Eloi Sylvester and union leader Charles A. Savarin were defeated by their DLP opponents, Michael Douglas and Romanus Bannis.
