Thanks to eight years of sustained economic growth Labour could point to a strong economy, with greater investment in public services such as education and health. This was overshadowed, however, by the issue of the controversial 2003 invasion of Iraq, which met widespread public criticism at the time, and would dog Blair throughout the campaign. The Chancellor, Gordon Brown, played a prominent role in the election campaign, frequently appearing with Blair and ensuring that the economy would remain the central focus of Labour's message.
