Can anyone identify this for me?

Might be a weed or might be something nice....?

Looks like perennial cornflower to me (Centaurea). Definitely nice if it is a cultivar or even if it is the british native one.

I agree with Ed

This is it in flower

A third vote for cornflower! :)

Ah yes of course! Thank you all so much. They've just appeared. Looking forward to the flowers.
Really appreciated! CL

And here is ...drumroll...the first flower! Thanks again all. Any tips on how I can spread these around welcome. CLx

I know this as knapweed.

It will spread by itself if happy.  I have blue, white, pale pink and deep purple forms and find babies which I leave or move depending on where they appear.
