UK - Most Europeans believe their countries are more polarised than 10 years ago, and 47% see their societies as less tolerant, a poll for the BBC suggests. In the online Ipsos Mori poll spanning 27 countries, 66% of people in Europe felt their nations were "more divided", the highest proportion worldwide. Politics emerged as the main cause of tension globally, being identified by some 44% of all 19,428 respondents. Half of Britons cited a divide between immigrants and nationals. It was the source of social division most commonly identified in the UK, followed by differences of religion (47%), ethnicity (41%) and political views (40%).
