Britain can withdraw its armed forces cover from Europe as noted in the Daily Telegraph. Just a small sample of bargaining chips available. 

And it also notes that the Scots support Mrs. May as per a recent poll and they do not want to vote for separation. This is why I subscribe to the DT because it de-slants some of the news in the WP and the G&M. And then there is Marine Le Pen and who knows what will emerge from the French presidential elections, phases 1 and 2. Also, there is news that a Swedish politician is thinking in terms of Swexit. Britain has its own currency, and this is an exceedingly important factor in making Brexit work for it, if not for the rest of the E-U. 

Britain will seek more trade agreements on its own while all this is going on. To read the G&M article it would seem no country could survive on its own unless part of a massive bloc. 

Britain will make its own rules and have more control over its borders and make its parliament great again. Not be held back.
