Of course they try. It's standard business everywhere. In the EU alone there's a combined "budget" of almost 2 billion for "lobbying" being used by a huge number of lobbyists. That number probably quadruples when all the "lobbyists" in regional and local governments are added. So YES, with that huge budget, there is bribery going on, but no one will call it that because it's a
bad word.

"At EU level, lobbying activities lack comprehensive regulation. The Council, for example, has
no system in place to protect itself from unethical lobbying."
