Why are 3 of the 4 component countries of the UK mentioned? They are not dependencies colonies or territories. If they are going to be included then why not England as well?
Could you also accept "Flying Fish Cove" for Christmas Island and "Zanzibar" (instead of the complete Zanzibar City) for Zanzibar?
Also Canary Islands have two capitals: Santa Cruz in the island of Tenerife (executive & legislative) & Las Palmas in the island of Gran Canaria (executive & judicial)
And so is Azores which has three capitals: Ponta Delgada (executive), Angra do Heroismo (judicial) & Horta (legislative)
And since Plymouth is a ghost town, you could also accept Brades and Little Bay as the capital(s) of Montserrat
