Luke Roberts to Leave?

It has been announced that Luke Roberts, who plays the brilliant Joseph Byrne, is set to leave Holby City in order to persue other acting roles.

It has been said that Luke has bee given a role in the new Pirates of the Carribean movie. 

I am totally devestated by this news, and I have no idea what will happen to JosepByrneFans on Twitter, so any ideas would be welcome.

Update with more info soon
