Hi,
There may be no need for a new tribe. Looking more closely at Theresa May, her leadership could be in the 'One Nation' direction to satisfy middle ground electoral deciders. Pundits will be aware that this centre ground is where Tony Blair won three elections in a row. It will be telling to see what she does with Osborne. We know that May was for 'Remain' and I believe that Osborne was/is genuinely so.
It is true IMHO that 'A house divided against itself cannot stand'. If May can do this balancing act, and make Brexit seem palatable to a worried half of the population, including (hopefully) a nod to maintaining some social justice in our island, then the Tories will win a fair majority at the next election. Let us remember that it was May herself who coined the warning 'nasty party' for the Tory leadership. She knows the price and the prize.
Labour are stewed. 
What a shame.
D.
