British nationalism asserts that the British are the nation as well as promotes the cultural unity of Britons, in a definition of Britishness that may increase people of English, Scottish, Welsh together with Northern Irish descent. British nationalism is closely associated with British unionism, which seeks to uphold the political union that is the United Kingdom, or strengthen the links between the countries of the United Kingdom.
British nationalism is characterised as a "powerful but ambivalent force in British politics". In its moderate form, British nationalism has been a civic nationalism, emphasizing both cohesion and diversity of the people of the United Kingdom, its dependencies, and its former colonies. However, nativist nationalism has arisen based on fear of Britain being swamped by immigrants; this anti-immigrant nativist nationalism has manifested politically in the British National Party BNP and other nativist nationalist movements. Politicians, such(a) as former British Prime Minister David Cameron, make-up sought to promote British nationalism as a progressive cause.
