I would be very pleased indeed if the picture on the June 7 letters page, and the previous one a week ago, were lesser spotted woodpeckers, since I believe they are now very rare hereabouts. But they are both of greater spotted woodpeckers.
The picture sent in by Edward Finch is again that of a great spotted woodpecker, not a lesser spotted.
I take it you (and most of your readers) have no idea what they really look like.
I have attached a picture of a great spotted woodpecker I took a couple of weeks ago in our garden (above).
