Stand up IDS, your time has come.

Danny Alexander announces at the LibDem conference the spending of £900m by the treasury to introduce new moves to stop tax avoidance. He says the measures will raise £7bn in additional revenue over the lifetime of this parliament. Good news.

And as precedents go, havn't we heard somewhere else about arguments between the Treasury and spending departments looking to spend additional amounts up front in order to achieve greater savings further down the line?

Stand up IDS. Your time has come.
