The UK coalition gov't eventually need to either increase the national debt beyond Maastrict treaty's restriction or increase the tax again

Well, I partially agree with your comment, my friend. But, speaking of the tax plan, it seems to be a "discrete" fiscal plan rather than a "permanent". During recession or recovering periods, they offer a temporary tax cut, but it sounds like going up again.

The coalition will have a dlilema about it. In terms of my prediction, as long as Britain sticks to Maastricht treaty, her economy hardly recovers.

Although I disagreed with Labour and Gordon Brown, the national debt should have been incured more before the recovery was ensured (without increasing tax which Labour and Gordon Brown insisted on 'cos of the restriction on incuring debt by Maastricht treaty) rather than introducing a temporary tax cut which concerns with the problem of Ricardian-equivalence (People already know the tax will rise in the near future so an effect of temporary tax cut won't work as much as the policy expects).

The first 10,000 quid you earn free of tax itself is fine. But, it does not seem to be effective enough when the total recovery from the recession caused by what the former gov't party Labour created!

I do usually not agree with incuring an extra national debt for a temporary recession, but the currently going recession shall be called the "depression" caused by the artificial economic boom plotted by Labour. The coalition gov't eventually need to either increase the national debt beyond Maastrict treaty's restriction or increase the tax again...

I do not put this comment to contradict you, but this is my worry about British politics for the moment, and I wish some gentlemen like you may listen to it...
