MPs are falling over themselves to reveal commitment to radical reform and satisfy what they tell us is public demand for people power, smaller parliaments, a chastened executive, fixed terms and proportional representation.

It is self-evident that the crisis over MPs expenses has precipitated the publicity drive for reforming zeal. It is also true that parliament is overdue for real change.

But this has been a Westminster conjuring trick worthy of Tommy Cooper. Into the hat went expensive rocking chairs, duck islands, wisteria clearing and some dodgy stuff with taxation but hey presto, out came a cuddly white rabbit called constitutional reform and every politician wants to take it home.

I knock on a lot of doors and in the last few weeks I’ve not met anyone who suggested that a fixed term parliament would have stopped an MP from flipping their second home or that being elected by a single transferable vote would make them think twice about buying an expensive plasma TV at the taxpayers’ expense.

Most of the voters expressing views (as opposed to abuse or apathy) have been more concerned with the morality and greed of individuals (or couples) than the constitution. That does not mean they don’t want reform but they do know it is a different issue.

The hard questions are not being answered. The cherry picking outrage of the press has done little to separate legitimate claim from dubious justification. Without a real debate about the role of an MP and some unsensationalised information about the duties of the job, the public is unlikely to have any influence on a new system of expenses or constitutional reform. This will suit some of those in office at the moment as they wait for it all to blow over so they can get back to normal. Those who want real change have to make sure it happens with public involvement and that means that politicians have to take the hit for misuse of the Additional Costs Allowance and not try to evade it.

The whole relationship between government and people needs to be aired and debated. If the Senior Salaries Review Board recommends large increases in salary to address the problem without a complete review in the public gaze, it will only leave the impression of the establishment closing ranks.

That is why MPs making pronouncements should be wary of coming to conclusions about the future shape of parliament without asking the electorate for some very basic information.

The questions should not start with ‘Do we want fixed term parliaments, primaries, fewer MPs etc. First of all: ‘What do we want from parliament and our relationship with politicians? This has to include working hours, constituency office arrangements, second jobs and homes and public engagement. Once that is established, the debate on the mechanisms can begin.

The debate has to be removed from MPs’ vested interests. The MPs’ view of what is desirable or acceptable to the public is what led parliament to the system of supplementing salaries with allowances and the tortuous justifications for claiming every penny they were ‘entitled’ to. The whole purpose was to pull the wool over the public’s eyes and that is at the rotten heart of our present system. It is imperative that none of us forget that lesson.

Party leaders who try to gain political ground by launching campaigns for this or that reform will make it harder for all politicians to regain the trust or respect of the electorate.

That means that leaders cannot choose who they want to keep or direct their fire only at party grandees who have outstayed their welcome. It means also accepting that individual accountability of MPs is what lies at the heart of our democracy, however flawed that is.

It would be hugely damaging for all politicians if the issue of constitutional reform were to be used as a distraction by MPs to avoid the consequences of their actions on one of the few occasions when ‘safe seats’ are probably irrelevant. It would also be a missed opportunity if MPs took all the decisions and asked for a rubber stamp as part of a manifesto package at the next election.

It is up to Labour to treat this one as an opportunity for real change.
