Wife Swap is back for a one-off Brexit special revealing what happens when a family of ardent Leavers meets an equally passionate family of Remainers. Pauline, Andy and 14-year old Katie live on Canvey Island - the area with the nation's third highest 'out' vote - 72% of the local population want to leave Europe. Bar worker Pauline will be swapping her home, job and family with psychotherapist and Green party councillor Kat, who lives in rural Nottinghamshire with her partner Roger and 17-year old daughter Sophie. Across one week these two strong-minded and opinionated women will immerse themselves in each other's lives and face head on deeply controversial issues around immigration, class and racism. Will they hear anything that changes their mind about Brexit? Can they persuade the other side that they were wrong? And what will happen when they come face to face across a table at the end of the experiment?
