The paper is devoted to the Great Britain's stance on the promoting of European integration towards creation of a federal state, after the euro crisis. It focuses on advantages and losses of the British policy in the EU. There are standpoints and views of four main political parties of Great Britain on the country's secession from the EU as well as the results of both local elections and elections for the European Parliament which reveal the rise of the right secessionist and anti-European moods in British society. The author also considers the European nations' present views and attitudes to the European idea. The following questions are answered in the article: Do the anti-European moods exert the crucial and lasting effect on British European policy? Is it better and more profitable for Britain to stay within the organization taking an active part in the integration process, or to withdraw from it?
