In its early years, the Party expanded through mergers with a number of smaller movements, including the British Defence League, a small group based around ex-
Conservative John O'Brien. Another group to join was the Association of British People, a 200 strong group from
Birmingham that opted for the NDP after turning down the overtures of the National Front's
Martin Webster. This group took the lead in the campaign in the
Birmingham Stechford seat where the party won 3.% of the vote in the
1970 general election. In the same election the NDP had managed the largest vote share of any far-right group competing in
Southampton Itchen, where it won 21.8% of the votes. Southampton was the seat of the
Speaker of the House of Commons however, and traditionally, re-election of the Speaker is unopposed by other major parties. With only 2.5% of the vote secured for its candidate in
Leicester North West, and although the party had attracted some disaffected Conservatives who supported
Enoch Powell, there was a general feeling within the NDP that the election had been disappointing for them. ==Relationship with NF==
