[Star Wars]How much power did Darth Vader have over Imperial politics?

Provided he has an intrest in it. For example he has always hated slavery. If he put his mind to it, could he stop the Empire from using slave labour or not?

Vader wielded a lot of power over the Empire, but in the end the Emperor had final say over his decisions. He was, after all, the second most powerful person in charge.Even he answered to someone. As for stopping something like slavery, only if Sidious had some incentive to let him do so. He is a master manipulator above all and can probably convince Vader to abide by his rules and wishes, which is how he kept him in check all this time.
