It's difficult to think of one of our current politicians who could qualify for the description "statesman".
I actually think that Theresa May had a golden opportunity to say "I wil stand up for what I believe. I do not regard the results of that advisory referendum, which was won by lies, as valid and so, as I have become Party Leader and Prime Minister, I will do what I truly beleive and ensure that the UK stays in the EU."
She would then have gone down in history as a true leader, a worthy statesperson and the PM who saved the UK from disaster.
Unfortunately she's blown it.
