News about Christopher Wren

Lesley Bellew boards the Viking Mars for a voyage from Greenwich Pier to Norway's Unesco-listed fjords. The 'adults-only' ship has a 'light-filled atrium', pianist, 'Norweigan open sandwiches' and offers views of seals, puffins and even an albino reindeer.

Geoffrey Munn (bottom inset), a member of the BBC's Antiques Roadshow, developed the brooch (pictured left, worn by Queen Camilla), which is one of a series of gem-set bugs, while he was the managing director of Fabergé egg specialist Wartski, which has two Royal Warrants. Camilla's bug was a recreation of his sons Alexander and Edward's pet stick insect, Sticky. Pictured right: Princess Margaret in 1963, wearing a necklace by legendary jeweler Carlo Giuliano, who became the cover star of Munn's book Castellani & Giuliano, on a discoss. Top Inset: Wartski made the Princess of Wales' wedding ring.

DOMINIC SANDBROOK: Charles I (left) was hardly a less convincing model for our own King. He was the worst possible ambassador for monarchy in terms of arrogance, obstinability, inflexibility, and sensibility. By contrast, his son Charles II (right) - despite his tumultuous private life, is a much more believable role model. He didn't have to cope with the humiliation of his father's public execution but he was also forced to hide in an oak tree after his attempt to regain the throne was foiled at the Battle of Worcester in 1651. Charles II is one of Britain's most underrated politicians. Many people were suspicious of a Stuart revival when he was called back to England in 1660. So how will the third Charles (inset) fare? Well, even if it sounds treasonous to mention it, another chopping block appointment appears to be implausible. No monarch in our history has waited longer for the throne or been more prepared.
