It's often said that the EU Common Agricultural Policy (CAP) is disadvantage to Britain, from the Guardian:
Britain’s withdrawal from the EU’s common agricultural policy (CAP) provides one of the few bright spots of Brexit, and if replaced with new legislation could help to restore some of the country’s degraded natural environment, one of the government’s leading economic advisers has said.
Dieter Helm, professor of energy policy at Oxford University, told the Guardian: “If there was any reason to be optimistic about Brexit, it is that it is the end of the CAP. It is hard to think how you could be anything other than better off if you had control of how you spend [the sums currently allocated in farming subsidies].”
I've found the following graph in an EU report on Agricultural and farm income:
It's often said, for example in this answer, that the CAP favours France, but it's unclear why. An obvious reason is that France has a larger agriculture industry (as supported by the graph) than any other EU country.
On the other hand, it seems a lot of criticism of the CAP comes from the UK, with the quote from the Guardian saying that the UK could better allocate funds for farming. The article goes a little bit into environmental improvements, but it's unclear to me why and if that's the major concern of the UK regarding the CAP.
My question is whether the CAP disproportionately disadvantages the UK compared to other EU countries (not just France, because it has a large agriculture sector) and what reasons contribute to that disadvantage. Or are other EU countries critical of the CAP as well and does it actually favour France over most / all other EU members?
