It might be cuckoo flower: cardamine pratensis?

It is indeed. Did not recognise it as the ones we used to see in Somerset were much redder than this one.
Thanks.

Its early isn't it? We used to call them Mayflowers.

I just wanted to add, I do think this is very pretty.

Likes damp places in particular, used to have it in the pond margins for years.

In Sussex we call them milkmaids. They like damp verges and woodland edges. Lovely little spring flower.
