Currant galls

I agree that the right hand photo looks like these. It may be in the other photo that the gall wasp has made its way out and the gall has shrivelled. Could also be that something has attacked the leaves which has affected the gall as well.
There's an oak in my garden with currant galls. Some have exit holes and are starting to shrivel slightly and lose their green and red colours. You're further south, so the gall wasps should have left earlier and the galls would be at a more advanced stage of decay.
