Lots of reporters on the Former Guy beat held on to important stuff until they were ready to release their books months or years after it would have had a policy impact. Woodward is the most egregious example. Maggie Haberman is another.

I fear that a big problem with the BoJo situation is that the power that be are going to spin this as a problem unique to him, rather than yet another example of how horrible the Tories as a whole are...

I hope Labour's current lead is enough to clean house soon (but my understanding is that elections are still years away unless something unexpected happens).

Good luck!

Cheers,
Scott.
