Prince William will do a two-day, military-themed tour of Estonia without Kate

It really does not look like the Princess of Wales will ever travel for work again. No more royal tours, no more overseas visits, no more day-trips to Denmark. Kate will travel, but only for pleasure. Only for vacations. Meanwhile, Prince William's next solo overseas trip has just been announced. He'll head to Estonia this month for a mostly military-themed visit. The Prince of Wales will carry out a solo overseas trip to Estonia this month, in his role as Colonel-in-Chief of the Mercian Regiment. Prince William, 42, will travel to the country in northeastern Europe from Thursday 20 March . . .
