Britain does not want to be at the heart of Europe - it wants to be in the EU, but not run by the EU. Even if the rebate went, the UK would remain outside any EU “core group” of countries, as it has chosen not to join the Schengen agreement on passport free movement, and to stay outside the Euro. Both these decisions have very wide political and popular support in the UK, and neither will be changed even if the rebate was weakly given away. So tensions will continue between Britain and its European partners, but at least by defending the rebate they will know that the UK is prepared to stand up for its interests and respect it.
