Money, love, professional jealousy - the three undying motives for personal crime, and all three were present in the Bolshoi Ballet acid trial. An international public that scoffed happily at the OTT ballet horror-show that was the film Black Swan was suddenly sobered up by real-life events that needed no cinematographers and screenwriters.

Are we seeing a breakdown in the ballet company system? Where the brightest stars used to twinkle in the great companies, all is changing. Alina Cojocaru, the great Royal Ballet ballerina, has announced today she's joining English National Ballet - run by another great Royal Ballet ballerina, Tamara Rojo. For ENB to have the two finest talents of the past decade in Covent Garden now at the head of their cast lists is the biggest stunner since… well, since the Bolshoi Ballet's young superstars Natalia Osipova and Ivan Vasiliev quit to join the smaller Mikhailovsky Ballet.

Last night saw the launch of the second edition of the enterprising MexFest at Richmix in East London– a celebration of all things Mexican (film, architecture, food and music in particular). The opening film was introduced by Baroness Jane Bonham Carter, the UK’s trade Envoy to Mexico, who announced 2015 would be Mexican Year in the U.K. which will showcase the best of the country's creativity.

As a prequel to the BBC's panorama of all things Tudor, Sunday night's new 10-part drama The White Queen (BBC One) whisks us back to the Wars of the Roses. Adapted from Philippa Gregory's novel, the series tells the story of how Edward IV, scion of the house of York, married the beautiful and widowed Elizabeth Woodville, from the rival house of Lancaster. In the opening episode, the pair first meet when Elizabeth (Rebecca Ferguson) petitions the king, as he rides past with his retinue, for the return of her lands.

It’s more pulse-quickening than a visit from Denmark’s actual prime minister Helle Thorning-Schmidt. This weekend Sidse Babett Knudsen, Borgen’s Statsminister Birgitte Nyborg, arrives in London to open Nordicana, an event dedicated to the ever-increasing amount of Scandinavian exports seen on our TVs. She will also be interviewed and take questions from the audience. Who needs real PMQs?

The celebrated star of the Bolshoi, Nikolai Tsiskaridze, has been told his contracts will not be renewed when they expire at the end of this month - an effective dismissal for Russia's flamboyant and outspoken ballet icon.
