Election Focus Group: how many 2019 Boris voters will back Conservatives now?

Cathy Newman: ‘After a month of election campaigning, are the politicians’ carefully crafted soundbites winning over the voters they’re aimed at?

When the major political parties want to find that out, they ask a carefully selected sample of the electorate called a focus group.

The polling company JL Partners has done the same for Channel 4 News, bringing together a group of swing voters from a Conservative held seat in West Yorkshire.

They all voted Tory last time but what will their verdict be now?

Our political editor Gary Gibbon listened in to find out.’
