HELP... Can Anyone name this one.? Seems a bit of a thug..!!!

My friend just sent me these photos of what he assumes is a stubborn weed.. It appeared last year in his stone corner.. it is low growing & has a purplish flower.. He let it flower as it was pretty, but now it is taking over...
I don't know what it is either looking at his photos. It hasn't flowered yet this year.


That is a watering can next to the stone with the leaf.



He tried to get the Kitchen scissors in the shot as an example of size, you can just see the handle in the bottom of the pic..

I have tried to get a closer shot of the leaves..


Any help greatly appreciated..

 

Thanks but I don't think so loli, I have thought it looked like several plants but no luck so far...
