I thought that Brexit was because the UK didnt want to keep paying Greece, Spain and Italy ?
The UK didnt want to send billions to the EU and instead spend it on the NHS instead ????
Cameron did not like paying into the EU funds supporting farmers (he had not that many) and paying into lower developed regions to help them catch up faster.
If I remember correctly, at the time of Cameron, Italy is already a net funder for a small amount.
But the Southern European countries got indeed a lot over time, but that lesseded when the East-European countries joined in 2004, because they got as well. The total amount increasing.
Ditching the possibility that what Cameron did was one big conspiracy plot to get out...
What triggered for a part Brexit was that Cameron demanded always something extra from the EU,
while at the same time not managing expextations at the domestic front what would be achievable.
That Eurozone issue, a Cameron not willing to help paying, channeled through bailing out Greece, the surplus profits made by also his banks and big investors...
His battle attitude perhaps most damaging in wakening up broader eurosceptic sentiments in the UK. That Greece issue, those financial irresponsible southern european countries a problem of the EU, but not the UK.
Sum it up into: the EU is a loser with stagnated liberal reforms in France and those southern EU countries... and we the UK should not be part of a loser... we should seek the minimal relation to use their very big single market.
That is the situation when he starts that last re-negotiation round to get more opt-outs from the EU.
Looking back... he better had never started that re-negotiation. It was doomed anyway. What did not prevent that the EU gave indeed some little things to him... for old times sake or so.
And Cameron's position has not been forgotten by the EU. The norns of fate were already spinning the threads of Brexit at that time.
