A little out of date, but I read this article with interest. It explains well how British political system is working for Britons.
Ignore the Chaos. Britain’s System Is Working.
The country does not escape its various political crises despite its constitution. It escapes these crises because of it.
Britain’s system adapts. The country’s constitution is a permanently evolving creature, worming its way through time, surviving by changing. Nothing is sacred, except the one rule that no Parliament can bind the next. A democracy can change its mind, and so must the constitution change.
