Article 50 will still be invoked as the Tories have a majority, but the Scots Nats and Lib Dems will vote “No”.
It’s Parliament voting on the negotiated terms of the Brexit that will be more contentious. The globalists will try and stall this as much as possible.
There are a lot of remainist Tories and the majority is only a slender one. I think the support of Labour may be needed to guarantee the vote. Corbyn has stated that he will vote to trigger it, but he may demand concessions in return, such as trying to stay in the single market, which is something a lot of Tory Remainers may also try to insist on.
