//And how many have been revoked to date, since we left, NJ?//
No idea. Probably none, but whether we’ve used the facility or not is of no importance – that’s up to the UK government. It’s the fact that we can that is important, but that’s something, it seems, that some people have difficulty grasping.
//What types of EU foreign policies do not require agreement by all its members…//
Take a look at this, Corby:

“In her first State of the Union speech, and in the section of the speech most applauded by the European Parliament, European Commission President Ursula von der Leyen called for the use of qualified majority voting (QMV) in areas such as sanctions and human rights.”
There’s much more to it than that opening paragraph, but reading on, there is no doubt that the requirement for unanimity in many areas of what the EU has assumed as its competences – including foreign policy - will move to QMV. Not, of course, in one hit. That’s not how the EU does things. Instead it will be achieved “salami style”, each step in itself only a small change from the status quo, but collectively the small changes adding up to massive movements of power away from national governments.
//…and do you have examples where the UK did not support a foreign policy adopted by the EU?//
No. As above, it’s not what is actually done, but what can be done that is important. Until recently the idea that QMV would extend to foreign policy was not a (publicised) consideration. If you're happy to see your country's foreign policy determined by foreigners then the EU is the place for you because it is clear that QMV will extend to an ever increasing number of areas - including foreign policy (salami style, natch).
