The Observer used to be a fine campaigning newspaper, although it has become a little subsumed within its Guardian embrace in recent years. Nevertheless, its editorial today provides the best, most vigorous response yet not only to the anti-High Court hysteria of last week, but also of the wider threat posed by a constitutionally blind right-wing movement across Europe.
In its dissection of the British constitution and its evolution, the editorial provides AS politics students with a masterly and concise overview.
In its attack on "the lie factories of Fleet Street", it offers a well executed broadside against the lethal exercise of power without responsibility that the mainstream press still has.
In its defence of the role of parliamentary sovereignty, it offers an articulate case for the virtues of that particular system.
In its linkage to the wider world of right-wing political extremism, from Donald Trump to the authoritarian clampdown of Turkey's President Erdogan, it offers a timely warning against the siren voices of the anti-liberals in our own country.
Finally, whether you agree with it or not, it offers a cogent critique of Theresa May's premiership so far - a premiership not yet affirmed by any general election result.
Today's Observer editorial is both a great campaigning piece and a well-articulated argument about our body politic that can be recommended to any reader, and certainly to the AS student in search of further, well-informed, debate.
