Encore Presentation - Whatever Happened to the Concept of Budget Secrecy?

Today an encore presentation of an episode that originally aired on April 2nd. There used to be a time when the finance minister's budget speech was the most closely guarded secret on the parliamentary agenda.  Not so much anymore. These days many budget policies are released weeks before the speech. That's certainly the case this year. The budget speech isn't for another few weeks but daily we seem to learn more about what will be in the speech. The Canadian correspondent for The Economist, Rob Russo, gives us a history lesson on budgets but also takes us inside this year's process.
