Because UK is still in EU and paying for it? They have decided to get out, but are not out, and the dues are still flowing in to "Junk"er.
Here is the very basic thing about democracy. The only real power democracy has ever had or ever will: The fear of the elected to get the boot next election. That is the flaw of the EU ruling class. They are not elected directly by the people. Being elected/chosen by elected people doesn't count.
While it's not a direct vote but a party vote, there is a vote for the EU parliament, at least I have voted for it once.
