History lovers can talk online this week to the Otley-based expert who helped identify the remains of Richard III.
Historical weapons expert Bob Woosnam-Savage was part of the team who recently confirmed that a skeleton found under a Leicester car park was that of the late king.
Mr Woosnam-Savage, curator of European Edged Weapons at the Royal Armouries Museum, used his expertise to examine the wounds on the skeleton and rule they were consistent with historical accounts of how Richard met his grisly end.
Tonight he will feature in a follow-up TV programme, Richard III: The Unseen Story and from 10am to 11am tomorrow he will be answering questions about his research work for the project on Twitter. Anyone interested in taking part should follow @Royal_Armouries and use #RichardIII.
