His statement includes:

“The consequences of the focus on my faith is that I have found myself torn between living as a faithful Christian and serving as a political leader. A better, wiser person than me may have been able to deal with this more successfully, to have remained faithful to Christ while leading a political party in the current environment. To be a political leader - especially of a progressive, liberal party in 2017 - and to live as a committed Christian, to hold faithfully to the Bible’s teaching, has felt impossible for me.”

If he can't reconcile his medieval religious beliefs with his party's progressive social policies how can he continue to function as a Lib Dem MP?
