Overview: Tonight's Newsnight will be on for a full hour - from 10.30pm to 11.30pm - as we pick over the details of what Chancellor George Osborne announced in today's Budget.
Iain Watson and Michael Crick will be taking us through the key measures, the political calculations behind the figures and possible flashpoints.
Paul Mason will be taking a wide view of the measures and giving us his analysis of whether it is as the chancellor claims a "Budget for growth".
We will be speaking live in the studio to Chief Secretary to the Treasury Danny Alexander, shadow chief secretary to the Treasury Angela Eagle, and the head of the Office for Budget Responsibility (OBR) Robert Chote.
We will be assessing what kind of chancellor Mr Osborne is with former chancellor Lord Lamont and economists Ann Pettifor and Irwin Stelzer.
And our Political Panel - Danny Finkelstein, Olly Grender and Peter Hyman - will be here to debate all that we have learned.
Plus, following the news that actress Elizabeth Taylor has died, Stephen Smith will be looking back across her life on and off screen and we will be talking to fellow Oscar winner Julian Fellowes.
