//OK, it wasn't a specific pledge but it created an expectation,…//
It’s just as well that the expectation was met, then. In 2015/16 (the fiscal year prior to the referendum) the annual NHS budget was £134.9bn. That’s £2,594 million per week. The current year’s budget (which, unlike the previous two years, does not include any specific allowance for Covid) is £173.8bn. That’s £3,342 million per week – an increase of £748 million per week over the 2015/15 figure. So over twice the "expectation" that was posted on the side of the bus.
//(a) Brexit is obviously not done…//
This keeps being repeated. In what way is it not “done”? As I said, the most important point is that the UK is no longer a member of the EU. That is irrefutable.
//(b) it is not necessarily the democratic will of the people as is often expressed.//
The argument about that is done. More people voted to leave the EU than voted to remain (and that was the only question they were asked). That was all that was needed. We left.
(b) it is not necessarily the democratic will of the people as is often expressed.
