We must listen to voices that disagree with us, and have an open debate about how we use our powers and remember that government exists to serve the power of the individual not the other way around … that is what keeps us different to those on the other side of the wall.

We face no concrete walls … sometimes there can be a sense that the great challenges have somehow passed and that brings with it a temptation to turn inward.
