Well at last they've caught on, and now what I've been repeating on this blog since 2007 is official, namely that the combined memberships of the UK's three main political parties is now fewer than 1% of the UK electorate (that's electorate, not population). A HOC library paper that passed me by in June has the detailed analysis.
They also suggest what I've long pointed out - that the decline isn't due to our general reluctance to pay subscriptions. The National Trust has 3.8m paying members, and even the Women's Institute now has more members than the Conservative Party.
So with the memberships of the big, central Statist parties in freefall, the public voting with their feet in droves and the people fed up with the lot of them, what do you imagine Christopher Kelly's recent inquiry concluded? Yep, that's right - that we keep the dying parties in their places with a tsunami of our tax cash. It's a bit like nominating the mummified corpse of Lenin as the next Russian president.
NB even the Commons figures are exaggerated; the number of Labour members not more than six months in arrears with their subs is probably 30,000 lower than the quoted figure.
