This free playwriting competition includes great prizes, such as a premier in London, 10% of the box office and a £6,500 commission for your next play. That's jolly good if you happen to be the lucky winner. I hope you are, but they'll be lots of people taking part, so you're just one small fish in a great big pond.
Unusually this competition offers something of value to every single entrant – feedback. If you have an interest in writing plays, I think it's worth jumping in the deep end just for that.
(I'm featuring a different free to enter writing competition every day from the 8th until the winter solstice.)
