On further investigation the small pipe going into the big one is from the bath waste. I filled the bath up and when I emptied it the dripping started getting quicker. Could it be blocked or the seal has perished on the joint ?

Good job finding it.  Yes it's likely a seal; you could pop it off and try to find a replacement.

I am not an expert but is that a crack on the grey plastic pipe? While you have the wall open, it might be a good opportunity to look to applying some sealant or something

It looks like that's already been done.

The rubber bung looks like it need replacing as per the ones in the link above, its worth checking that the pipe is long enough to be seated all the way in, or that it hasn't managed to be dislodged during install or boxing in
