By the standards of June, when nothing much can tends to happen as people start to enjoy the weather in the UK and stop thinking of ways to upset everyone else, there is a small political bomb being planted today.
Led by the combustible Ed, a speech is being made now at Reuters that suggests an incoming Labour administration in 2015 will be an austerity government. With a pitch that seems to clash badly with previous positions, Labour are to note that there won't be any money left and most departmental spending will have to continue to come down.
Furthermore there are gimmicky ideas on tax raising such as reducing winter fuel payments for elderly relatives and also increasing the whole bankers bonus tax. These two idea raise in the grand scheme of things next to nothing in real revenues, but help to position Labour firmly on one side of the class war they are so intent on continuing.
It is far from certain that Mr Balls will ever get any economic credibility. It is a strange world in that both Osborne and Balls are in dire need of replacement by their party leaders, yet neither one has the courage or political capital to act.
In the longer term, this is quite a shrewd move by Labour. For on most other policy fronts they lead the Tories by a healthy margin. If they can get some ground back by promising Tory economic policy only from them, just as they did in 1997, then this could prove to be a turning point in their fortunes.
The Tories though will be able to point to their flip-flopping (whilst carefully ignoring their own implementation of plan B rather than A). Interestingly the truth is that both leading parties have almost the same ideas on the economy now, both seeking an austerity-lite package. The opportunity for the Liberals and UKIP to offer a different package is their for them to seize.
