I think Monday and Wednesday may show a joining of forces in parliament, as the EU is making it quite clear that an extension has to have a good reason, and the EU are sharpening minds by reminding the UK that No Deal is on the table, and they are more ready than the UK.
The EU will want to see a plan, which works in their interest too, and I think their talk over the last week, could well help members join together behind one option (in my opinion a hybrid of the most popular from Wednesdays votes) which could convince the EU.
However the EU, I imagine, will only grant the extension, if the plan put forward is one likely to lead to a revoke/closer tie. They will not want our MEPs round the table if we are likely to leave soon into the session.
The MPs will know this, and I think enough will draw around a hybrid between the most popular initiative votes, to give us a shot at the extension.
