Piltdown, spare me your indignation. You opened up with "Some unaccountable, greedy career politician and his cohort of overpaid lackeys will do ONE deal for EVERY EU country...." and further suggested corruption. If you don't like your ignorance challenged, then don't display it.
Trade deals must be approved by all national parliaments and by the European Parliament. All of which consists of democratically elected members.
Likewise the EU Commission where the President must be approved by the European Council and the European Parliament, The same goes for the commissioners.
Now tell me, who elected Therese May as PM?
