Nick Clegg made few references to the Conservatives in his speech yesterday, other than to praise David Cameron for helping to build a "new kind of politics".

But there was also a little-noticed dig at the Tories' election campaign. While discussing the "new politics", Clegg declared:

Never again will anyone be able to frighten the voters by claiming that coalition government doesn't work.

That was a thinly veiled attack on the Tories' cynical "Hung Parliament Party" broadcast, which warned that a coalition would lead to "behind-closed-doors politics", "indecision and weak government" and "a paralysed economy".

For Clegg's sake, perhaps it's just as well that most of the speech could have come from any Cameron address.
