ID this weed please

[Darkblueskies]

I know nothing about gardening. What is this weed which is suddenly everywhere I look?
Thanks

looks like a doc leaf to me - long single root?

Not dock, I think it's that one with a pink flowers. No idea what it is called.

Rosebay willowherb?

Ooh if it is rosebay willowherb at least it looks fairly nice. Since it is everywhere!!!

Rosebay willowherb.

Thank you everyone.

It might have a lovely name but if I were you I'd get busy pulling it out if it's everywhere. It's a prolific self seeder and the flowers are very short lived.
