I'm sorry but this article falls into the category of "We knew it all along". This is information that MI6 SHOULD have handed the white house during his candidacy. If MI6 had access to this information, then, if anything, it shows that GB as our strongest ally didn't care or at worst, supported Trump's rise to the White House knowing what he was. I'm not certain if the purpose of this article is to paint a better picture of Trump or to give the UK a black eye as the US's ally. It's too late now and the man is in office.
On the bright side, assuming he's not impeached first, anyone opposing him in the next election will only need to point out how much he's lied to the American people to triumph.
