What does it mean when I read that the Irish gov't will "be dissolved" after this bailout?

Confronted with high-level defections from his governing coalition, Prime Minister Brian Cowen said he would dissolve the government after passage of the country’s crucial 2011 budget early in December.

I don’t understand the depth of this, can you explain?

Thanks!
