Does England have a king and a queen?

When (if) Charles comes to the throne after his Mother Queen Elizabeth passes away, he will be king regnant and his wife Camilla will be queen consort. Buckingham Palace has indicated that when (and if) Charles ascends the throne, Camilla shall be styled Princess Consort. Therefore a King and Queen may not occur until Charles son The Duke of Cambridge and his wife the Duchess take the throne.
