Weed or plant??

[DailyFailAreTwats]

What do you think?

Not sure. I would wait and see, or wait for a more helpful answer.
If you don't want it then treat is as a weed.

Difficult to tell - how big are those leaves?

Could be fat hen?

How tall are they?

They aren't tall, about the height of a geranium. They are only appearing in one but if the border (we moved in recently) so look as though they belong there... but might be lying...

I would wait to see if they flower. If they bother you, get out the glyphosate.

Looks like a weed

a weed is a plant you don't want where it is.

I would wait until it flowers and then decide if you want to keep.

no, no, no don't use glyphosate or other weedkillers.
evil stuff.
dig it out and compost it if you don't want it.

No to glyphosate . Kills wildlife and harmful to humans, like all weed killers.
