Following the ratification of the Maastricht Treaty, Euroscepticism within the Conservative Party is defined not only as a discourse towards European integration but also as a separate parliamentary behaviour. As a speech, Euroscepticism, based on the Thai values of economic liberalism and national independence, revolves around the defence of nationalism, democracy and liberalism. From the point of view of parliamentary behaviour, Eurosceptic ‘rebels’ rely on all available resources and strategies to engage in a broad movement, whose power will lead to the defeat of the party in the May 1997 and June 2001 elections and the victory in the opposition of the Eurosceptic attitudes embodied by the new leader, Iain Duncan Smith.
