David Cameron’s thoughts about constitutional reform published in the Guardian this morning are a mixture. Some of them are good, such as giving MPs themselves more power over the composition of Select Committees. Some are good, but not exactly fresh, such as having local authorities take over public facilities like Post Offices in the public interest. A Conservative council, Essex, is already doing this, with the support of Labour ministers. Most ideas (as with the Constitutional Renewal Bill that Labour came up with) are inconsequential or gimmicky. It is ridiculous to talk of SMS text alerts on the progress of Bills, or parliamentary committees on YouTube, as being radical constitutional reform.

Cameron is most disappointing when he makes it clear that he intends to do nothing about the most basic method of making parliament accountable – the voting system. He trots out a number of tired clichés about ‘the man and woman in the street’ having power under the current system, and (yawn) ‘secret backroom deals’ under PR.

Whether ‘the man and woman in the street’ has power under the present system depends entirely on what street they live in. Two thirds of the country is effectively cut out of the national debate because they live in safe seats. Even people who are nominally candidates for these seats are encouraged – ordered, even, in the Conservative party – to work in neighbouring marginal seats. If the street you walk down is in Swindon, you have power, and – provided that the sophisticated marketing software the parties have tells them that you might be persuadable – Cameron and Brown are interested in you. If your street is in Sheffield, or rural Suffolk, forget it. One can easily guess where most of the burden of ‘austerity’ is going to fall, and it’s not going to be on those with political or economic power.

Safe seats make for a cosy life for the political elite. The current electoral system produces a lack of choice for voters; they have to accept the candidate their party provides them locally, or vote for a party they do not support. Barriers to entry in the political market place are kept high, and that is the way Cameron likes it – no challenges from cheeky upstarts like UKIP or the Greens to the big boys. Cameron seems to believe in monopoly provision not choice in this public service.

Cameron also fails to mention reforming the House of Lords. Many Conservatives, such as Ken Clarke and William Hague, have favoured an elected second chamber with no single party in control, making it an effective check on the government. Now Cameron seems to be saying nothing. Perhaps he is getting increasingly comfortable with the idea of a second chamber as a retirement home for members of the political classes, and less interested in challenges to executive power.

Cameron’s ‘reforms’ are clearly designed to do just enough to satisfy the current mood for change, while preserving the essentials of the current system so that they can enjoy the excessive power that can be bestowed by as few as 36% of those voting under this system. He promises only the most superficial re-spray of our dangerously decrepit political machine before he installs himself at the controls.
