"Labour forced a division on its motion on beefing up the ministerial code (see 1.48pm), even though the government was not voting against. (You can do that by getting someone to shout ‘No’ when the Speaker calls the vote, and putting up tellers for the no side.) The motion was passed by 215 votes to 0."

I am sure there is some subtle advantage in doing this, but I don't see it at the moment.   Something to do with getting the names of every who voted and didn't vote for it recorded, I presume, which, long term, might play into a "did your MP vote to toughen the rules?" in a campaign. Remember that in a division the bells will be rung so everyone in the House or their office will know a vote has been called, and they will then have to explicitly choose not to attend.

But it all seems a shade tenuous.
