I did wonder..

..about Sonchus arvensis, but rejected because of auricles and I couldn't see glandular hairs. But it's difficult to tell on this rather indistinct photo.

I think I can guess them on

I think I can guess them on the first pic, against the black background, but it is not that clear I agree!

A couple of points ...

... favouring Sonchus arvensis are the "shaggy" capitula, and the barrel-shaped buds (the buds are conical in Sonchus asper and Sonchus oleraceus.

I would have said that the first picture was an obvious Sonchus arvensis and that the second picture was a bit ambiguous.
