Britain's 'In' campaign has highest lead since January - JPMorgan poll analysis

JPMorgan said the campaign to keep Britain in the European Union had a 7.6 percentage point lead, the highest since January, when recent opinion polls were filtered to remove methodological and statistical effects. "Fitting a statistical filter to the weekly data to try to screen out the noise points to a 7.6- point lead for 'remain' based on the data in hand, the largest lead since late January," JPMorgan said in a note to clients.
