Here is a poetry competition which I can wholeheartedly recommend poets to enter.
First of all, it's free. Red Squirrel don't believe in charging for entrance to competitions.
Second, when I did it last year, it was a thoroughly wonderful experience from start to finish. I met the judges and heard them talk about the care they had taken to read and consider all the entries. The competition attracted work of a very high standard, so to be included in the anthology as I was, is a very affirming event. The organisation was terrific, and the award-giving was a warm and friendly occasion when we got to meet not only other Red Squirrel authors (likewise friendly and very interesting people), but also the staff of South Shields library and James Kirkup enthisiasts who turned out in force.
So if you've ever submitted your poem and paid £5 for the privilege (and more, sometimes, this year), only for it to disappear into a black hole, try this. No-one could guarantee prizes, but you can be sure you entry has been given all the care and respect you could want.
