The PM is perfectly entitled to give a final chance for her deal or say it will be long extension
Extension short or long will both already have been discussed with or at EU
Any alternate approach would take time to negotiate so indicative votes not magic solution
Far from being a disastrous / dreadful / shocking blah two days in Parliament, MPs have collectively started to think for themselves, and Government has started to respond. Long way to go though
PM not putting the same matter to the House a third time, might be the same deal (will be, whatever Vienna Convention tosh is talked) but the wrapping (extension to June if passed, longer extension if falls) makes this perfectly allowable.
