Each of those votes was a motion, rather than legislation.
The current position re legislation is that we leave the EU on March 29th, regardless of whether a deal has been reached or not. The relevant law was passed by the same Parliament that held the three votes you refer to.
May's deal cannot possibly pass. I was stunned to see it lose by only 149 votes, considering it was completely unchanged from it's previous attempt (where it lost by over 200 votes). Pro-remainers will rightly say that it is worse than the terms of our current EU membership, and pro-brexit opinion is that the deal does not see us leave at all, so is not worth supporting.
Presuming it fails, May will approach the EU asking for more time to ram the deal through Parliament. They will agree, in order to prevent the UK leaving on March 29th. May will then have to table new legislation in Parliament to get the date of departure varied, because it is currently determined by statute... and she will have to get that legislation passed BEFORE March 29th. If it does not get passed in time, we will leave on March 29th.
Cheers, Tree.
You have put it into layman’s terms much better than the professional journalists on TV
