It's a creeping buttercup. The shoot in the top right of the photo will soon root into the ground and produce another plant! They can be a pest in the garden.
Indeed creeping buttercup, it's an amazingly loyal plant, despite all our crazed efforts it comes back 😠😠 Dig it up asap making sure to remove all the roots, then offer a small sacrifice to your favoured god and keep your fingers crossed. I jest clearly but I have major problems with this as it was totally endemic in the old meadow that became our garden and it creeps in from the grass constantly
