The Wine Turns Sour
There's an element of mythology to the belief that the UK constitution is an unwritten one. It is possible to read it - if you know where to look. To save time, you can read the constitutions of one of the other countries that use the Westminster System. Canada or Australia will do but there are others too.
One of its essential elements is that it is a system of democratic representation - a cornerstone that was best summarised by Edmund Burke in his famous speech to the electorate of Bristol. You are probably familiar with the phrase but in case you aren't, here it is.
"Your representative owes you, not his industry only, but his judgment; and he betrays, instead of serving you, if he sacrifices it to your opinion."
The idea that the enthusiasm of the populace needs to be curbed is one with deep roots. In the classical world Plato argues that too much democracy inevitably leads to dictatorship and that is also the main theme in Shakespeare's Coriolanus and some of his other dramas.
Until the European referendum of 1975 the thought of asking the electorate to decide on a single issue was antipathetic to British politicians and it's worth noting the circumstances that led to that referendum as they are surprisingly similar to those that led to the current vote.
Back in 1972 as the European Communities Bill made its way through parliament Labour was badly split. The majority of the parliamentary party supported joining the Common Market while the unions, the national executive and the majority of the grass-roots troops were fiercely opposed to the "European Capitalist Club" as they called it.
In an tactical manouvre to convey a false image of unity the political party supported an amendment to the measure calling for a referendum - an amendment that was sure to fail.
The tactic worked too. What harm, then, in using the same idea when drawing up the party's manifesto for the election of February 1974 - an election that nobody expected Labour to win? The referendum was meant to be an empty promise that wouldn't need to be actioned - but Pandora's box had been opened and the cat was out of the bag, and when Labour were elected into government they had no choice but to go ahead and do it.
Harold Wilson succeeded to with the vote through a show of re-negotiating Britain's terms of membership and a lot of scaremongering but a precedence had been set. That precedence led to the two referenda in 1979 that deferred devolution in Wales and Scotland for a generation.
Now let us look at today's situation. Like Wilson's, Cameron's promise to hold a referendum on membership of the EU was an attempt to ensure unity within his party. There's no need to be a complete cynic to believe it was his intention to drop the idea immediately during talks for a second coalition with the Liberal Democrats.
But again, like Wilson, Cameron won an unexpected majority and painted himself into a corner on the issue of holding a referendum. The difference this time is that the mock-negotiations and scaremongering have yet to convince the electorate.
If the opinion polls are correct, and that's a big 'if', a parliament where three quarter of the members are in favour of remaining in the EU are about to be forced into passing laws against their will - and all because of the folly of a Conservative that forgot his conservatism.
I mentioned Plato earlier an I'll finish by quoting two other great philosophers, namely [musicians] Caryl Parry Jones and Myfyr Isaac! "If there's someone listening to my song down the wire, the play soon turns sour when playing with fire."
