Current state of Ex-RAF Harries?

Just a few questions, after reading a post on this forum, is it true that the current state of the RAF’s Harrier fleet is that they are in warm storage? in case of a return to service……………

Question 1. Where are they? Witt?

Question 2. Surely there is no real possibilty of then returning to service?

Question 3. How long are they to be held there?

Cheers
