Inside world's most luxurious cruise ship

The Regent Seven Seas Explorer will be launched today in Monaco before setting off on its maiden voyage on July 20.

It will be christened by Princess Charlene of Monaco.

The fourth addition to the Regent fleet can hold 750 passengers, but all of them will have to be wealthy - a ten-night cruise onboard costs more than £27,000 per person.
