Parliamentary Soveregnity is a good thing, very dangerous but good, things get done . UK is a Stable country therefore it kinda works, giving so much power to the Government.
But it leaves too much freedom and secrecy for those would would like to abuse it, high majority through FPTP (and Whip System) guarantees passage of bills. Codified Constitution would merely be some sort of collection of cardinal rules and rights that do exist even today.
I wouldnt want entrenched constitution like American One (although that one is Genius, written by geniuses)
