There has been a stark drop in support for leaving the European Union in member states across the continent in the aftermath of the Brexit vote in the United Kingdom, new data shows.Support for leaving the EU fell in every member state for which results are available across that time period, led by a drop of 11.8 percentage points in Finland, 10 percentage points in Slovenia, 8.8 in Austria, and 8.6 in Portugal.This happened during years in which Britain was mired in difficult negotiations regarding its exit from the union that underlined the complexity of leaving, while the country faced political turbulence and economic headwinds blamed partly on the disruption of its relationship with its biggest trading partner.The proportion of respondents who said they would vote to remain in the EU rose by 14.8 percentage points in Finland, 11.2 in the Netherlands, 10.5 in Slovenia, 9.7 in Czechia, 8.2 in Hungary, 8.1 in Portugal, 7.5 in Italy, and 6.7 in France.The results emerged in the latest edition of the European Social Survey, an academic research project headquartered at City, University of London, which has polled tens of thousands of people on attitudes and behaviours in national surveys in 30 countries across Europe since 2001."
