English Constitution 101 - Lesson 1: Procedures of the Houses of Parliament
What is happening is the Committee stage of the Bill. Every Bill goes through it in each House of Parliament, between second and third reading. Normally the Committee is formed from a cross-section of members representing the various parties in parliament and it sits over a few weeks in a committee room. Occasionally the whole house sits as a Committee - which is what is happening at this time. For government bills, it is a convention of the constitution that the government is allowed to control the passage of the bill and manouevre over different amendments, some of which are introduced by the government and bill supporters and are 'friendly', sometimes opponents of the bill introduce wrecking amendments which if passed the government will try to overturn later.
After the committee stage, the Bill returns to debate by the whole House for the third reading. This is when the Bill as amended by committee is further revised and the principles behind the Bill considered again. This is the stage at which principled opposition to the passage of the bill is attempted.
Then the whole process is repeated again in the other House.
Contrary to claims in earlier posts, there was no vote on the substantive issues of the Bill on the 3 November - a series of amendments by the opposition parties (Tories and LibDems) were voted down. Over 140 MPs failed to vote in the committee.
I'm sure Galloway would have preferred to have been there - but he wasn't to know when his speaking engagements were fixed that the Committee stage would be happening. I still fully expect him to be in the house for the third reading - and if he isn't criticism will be justified. Until then, it remains the usual knee-jerk Respect-bashing with little regard to the issues.
