Given that 1 is a rumour that was published in a newspaper who later admitted that they were publishing an unsubstantiated and un-researched probable non-story on the grounds that they were simply drawing attention to the fact that there was a rumour, possibly changing at a stroke the need for some evidential backing to front page headlines and plunging us further into post-truth - then this should be what is remembered. Even though he may not have done it. Also, as Cameron was about to launch remain it was a clear ploy to undermine him, remain and acted as a starting bell to the wholesale disinformation and outright lies fed to the British public prior to the referendum. It stands as a milestone in the death of representative democracy and the honest media that underpins it.
Now 2 is also quite important. But that will be blamed on another bunch, who will no doubt be vacationing somewhere with a strong economy (Europe perhaps) after pocketing millions from their billionaire paymasters for services rendered in destroying our economy and freedoms to ensure the mega rich can be richer, with trickle up in evidence. Davis, Gove, Farage, Boris et al just in case you were wondering.
