I have been emailed and asked for a sort of summary about the “UK-economy-repair”-subject.
For those interested I place the answer here, too:
So just to sum it up from the rules point of view:
It has been pointed out:
@rulebook:
Each of United Kingdom Europe and Pacific makes its own separate purchases and repairs.
…
An economy whose capital is held by the Axis can’t collect income, spend IPCs, or repair units."
So assuming Calcutta is in Axis’ hand and there is a damaged UK-battleship in the Pacific,
these are the questions and answers to solve the scenario:
Q: Who is the player who controls the damaged battleship?
A: It is the player controlling UK with its two economies.
Q: Does the UK-Pacific economy have a Purchase+Repair Phase?
A: No, because Calcutta is in enemy’s hand
Q: Does the UK-Europe economy have a Purchase+Repair Phase?
A: Yes, because London is still British
Q: So when and where can the damaged battleship be repaired?
A: During the Purchase+Repair Phase of the UK-Europe economy at every friendly operative naval base except British naval bases belonging to the UK-Pacific economy.
Also:
The loss of a capital does not affect the operativeness of any Naval Base. But it eliminates the Repair-Phase of that power.
So any (Non-UK) nation can use any friendly operative Naval Base, as long as the owner of the damaged ship has not lost his capital.
