Lib Dem Tim Farron quits as party leader - a sign of an ill-liberal society for people with faith?

Liberal Democrat leader Tim Farron quit as party leader yesterday. He blamed the tension between living as a 'faithful Christian' and serving as a political leader. So is he right? Or is this a sign of an increasingly ill-liberal society for people with faith? And are there lessons for politicians in Northern Ireland from Tim Farron's story? Kevin Maguire, associate editor of the Daily Mirror, and Peter Lynas of the Evangelical Alliance discuss.
