Interestingly while it'd be daft to call them Christian Nationalist the Labour Party does owe a lot of its early philosophy to various religious groups descended from the English Dissenters. This is also true for many groups that'd fall under the Christian Nationalist label in the US, even though their politics are very different.

Of course this just shows the English Dissenters ended up being quite influential on both the left and right over the course of Anglophone history.
