All recent polls on the sibject indicate that there is now a majority against leaving the EU. That is especially true among the young - in 2016 the voting breakdown among 18-30 year olds was 70-30 in favour of Brexit. The number of young people who have come on the electoral roll since then is several times as large as the Leave majority over Remain back in 2016. The only peole calling for a fresh referendum are Remainers, those opposed to one are virtually all Brexiters.
