The EU treaty?

A lot is being made at the EU Constitution Lisbon Treaty is being carefully debated and scrutinised in Parliament.

What's the point?

Both Labour and Liberals have broken their pledge of a referendum.

They cannot alter not one line, one word, one letter, one comma, one iota of this document.

Labour MPs—who have a substantial majority in the House—are under a three line whip to vote for ratification of the Treaty.

Thus simple question what is the point of this?
