Since the late 20th century, the exploration and proliferation of Britishness became directly associated with a desire to define, sustain or restore a homogeneous British identity or allegiance to Britain, prompting debate. For instance, the Life in the United Kingdom test—reported as a test of one's Britishness—has been described as controversial. The UK Independence Party have asserted that Britishness is tied with inclusive civic nationalism, whereas the Commission for Racial Equality reported that Scots, Welsh, Irish and ethnic minorities may feel quite divorced from Britishness because of ethnic English dominance; Gwynfor Evans, a Welsh nationalist politician, said that "Britishness is a political synonym for Englishness which extends English culture over the Scots, Welsh, and the Irish". Historians Graham Macphee and Prem Poddar state that Britishness and Englishness are invariably conflated as they are both tied to the identity of the British Empire and UK; slippage between the two words is common.
