Ox-tongue, Picris echiodes. Not a thistle, but in the daisy family,
as are dandelions and thistles. It has rough leaves with spines
growing from pimples on the surface of the leaf - very characteristic.

Looks about right. Do a Google images search on Picris and see what you
think - not easy to find pics showing the leaves, though.
