The Eurosceptic party had been led since 2002 by Roger Knapman. Although he was entitled to stand for second term of office on the expiry of his four-year term, he decided not to, claiming that he was too old for the post.
Richard Suchorzewski, the Chair of UKIP Wales, had defected from the Conservative Party in 2004, and called for the party to develop greater internal democracy, with the formation of a governing committee who would liaise with members on policy initiatives. He also wanted to prioritise the recruitment of more members under 40 and for party leaders to be based permanently in the UK. He attracted the backing of former chairman Petrina Holdsworth.
David Campbell-Bannerman was a former Conservative Party councillor and former chairman of the Bow Group, who had joined UKIP in 2002, and became its chairman in early 2006. He also called for the party to broaden its policies, and wanted to focus on democracy and freedom from government interference. If elected, he wanted to work alongside Farage, who he hoped would remain the party's leader in the European Parliament.
David Noakes, a computer consultant, called for the party to strengthen its focus on anti-EU campaigning. He stressed his belief that the European Union was equivalent to a police state. He called for co-operation with trade unions to organise an anti-EU general strike and for creating a permanent protest outside the British Houses of Parliament with a van broadcasting the party's message.
