it is the remainer MP's who are being obstructive
You mean like the 100 plus ERG members like the well known remainers Mogg, Francis, Davis etc etc.
No they are leavers and are rightly being obstructive because Theresa May is not delivering a good deal.
She was wrong in calling a general election, wrong in not sticking to the plan within the first week of negotiations.
We must stop blaming MPs, however obnoxious, the fault lies at the head and with the head who stubbornly refused to stand by her no deal is better etc etc and her strong and stable and her Brexit means Brexit.
MPs have behaved disgracefully but it's not just remainer ones. The leavers who betrayed their principles and voted for this awful deal. Had they stuck with what the public voted for then parliament would not have rejected a no deal and we would be out now, paying nothing to the EU, deciding who can come, passing our own laws etc etc. And the useless May would be history and our party would be in a strong position with Labour confined to the dustbin of history.
