The World Premiere of Game of Thrones' fifth season takes place on Wednesday 18 March, and we've teamed up with Sky Atlantic to offer RTS members the chance to win one of three pairs of tickets to the exclusive screening. 

You and a friend could be walking up the red carpet to be among the first to experience episode one of this brand new season of Game of Thrones in a truly historic setting, a full month before the rest of the world...

The premiere takes place at the Tower of London and it promises to be a night to remember. The Tower has seen its fair share of plot twists and treachery, so seems the perfect place to host the premier and welcome the stars of Game of Thrones to Europe. 

Since launching in 2011, Game of Thrones has become a bona fide TV phenomenon, keeping viewers guessing with a string of headline-making twists and turns and, as is tradition, the producers are keeping tight-lipped about what's to come. 

And now lucky RTS members have the opportunity to rub shoulders with the cast, while watching the opening episode of season five inside the iconic tower.

To be in with a chance to win a pair of tickets simply answer the following question and send your answer, your full name and your RTS membership number to competitions@rts.org.uk by midday on Thursday 12 March. Please be aware this competition is ONLY open to full members of the Royal Television Society.
