Two white butterflies

... but are they both large whites?  I rather struggle with this.  I'd say that the one on the right is a large white, but what about the one on the left?  Is that also a large white but one that is newly emerged?  Maybe!

I've had a bit of a day off today - shopped this morning and cut the grass this afternoon.  I've needed a couple of naps too.  Rain is forecast tomorrow so I thought I'd try and cut the grass while it is dry.
