National suffered its worst-ever electoral defeat in the 2002 election, gaining only 27 of 120 seats. Many hoped that English would succeed in rebuilding the party, given time, but a year later polling showed the party performing only slightly better than in the election. In October 2003 English gave way as leader to Don Brash, a former governor of the Reserve Bank who had joined the National Parliamentary caucus in the 2002 election. Under Brash, the National Party's overall popularity with voters improved markedly. Mostly, however, the party achieved this by "reclaiming" support from electors who voted for other centre-right parties in 2002. National's campaigning on race relations, amid claims of preferential treatment of Māori, and amid their opposition to Labour Party policy during the foreshore-and-seabed controversy, generated considerable publicity and much controversy. Strong campaigning on a tax-cuts theme in the lead-up to the 2005 election, together with a consolidation of centre-right support, may have contributed to the National Party's winning 48 out of 121 seats in Parliament. National, however, remained the second-largest party in Parliament (marginally behind Labour, which gained 50 seats), and had fewer options for forming a coalition government. With the formation of a new Labour-dominated Government, National remained the major Opposition party. Before the leadership of John Key, the National Party had made renewed efforts to attract social conservative voters, through adoption of anti-abortion and anti-same-sex marriage policies. In the 2005 general election run up, it was revealed that the Exclusive Brethren had distributed attack pamphlets critical of the Labour party and praising of National to letterboxes throughout New Zealand. Labour insisted that National had close ties to and prior knowledge of these attacks, which was repeatedly denied by National. It was later admitted by the leader Don Brash that he indeed did have knowledge of the plan, a statement that was contradicted by MP Gerry Brownlee who subsequently denied the National party had any foreknowledge. After the 2005 election defeat Don Brash's leadership of National came under scrutiny from the media, and political watchers speculated on the prospect of a leadership-challenge before the next general election due in 2008. Don Brash resigned on 23 November 2006, immediately before the release of Nicky Hager's book The Hollow Men, which contained damaging revelations obtained from private emails. John Key became the leader of the National caucus on 27 November 2006. Key fostered a more "centrist" image, discussing
