What's this weed?

[stroller]

Found this in my linseed, any ideas what it is?
Is it worth having a sticky thread for weed ID?

Hard to tell as pic is out if focus but some kind of euphorbia? Is the sap milky?

 

[stroller]

Didn't realise it was out of focus the sun was too bright to see the screen!

Ya, euphorbia, seem to get lots in bird seed. Put the sap on your warts but watch it as it’s also makes you photosensitive.

I have lots of this growing in my garden. Surprised to see your linseed is still flowering.
