News of their plot emerged as Mr Brown gave an upbeat performance at Prime Minister’s Questions, provoking supportive chortles on the Labour benches with jibes at David Cameron’s incomplete grasp of his party’s pro­posals to bring about a tax advantage for married couples.

It should have been a positive sign to the country that the Prime Minister had found a way of attacking the Conservatives on policy issues and was relishing the coming election campaign. Instead, it was immediately undermined by emergence of the plot by the hapless Hoon and Hewitt.

Their public confirmation of the depth of despair over Mr Brown’s leadership among MPs ensured that it was the Tories who were laughing. Nevertheless, it raises important issues about the electability of the Labour Party, given the lack of support for Gordon Brown’s leadership.

That is nothing new; it has been deeply damaged by the Blairite/Brownite faultline. Five months before the final cut-off for a General Election, however, is no time to force a leadership challenge.

Two former ministers who are not seeking re-election and are said to be disappointed at not being offered a European job will carry little weight, but their debacle has inflicted unnecessary damage to their party. The length of time it took senior cabinet ministers to express support for the Prime Minister and their failure to do so resoundingly suggests that Labour MPs have yet to close ranks, despite the approach of the election.

As the country struggles to cope with the disruption caused by the exceptional winter conditions, the people are looking for firm, practical leadership to ensure roads are kept open, danger is minimised and the vulnerable are protected. In the longer term, they want fiscal policies to take us out of recession and provide economic stability, and the polls suggest Labour still has significant support on those issues.

The expenses scandal angered voters because it demonstrated how out of touch many MPs are with the reality of their constituents’ lives. Their confidence will not be regained by a political party which indulges in political navel-gazing at such a crucial time.
