I have been trying to work out if I do have clutch slip or something else
My main reasoning for not being convinced is the total lack pf smell from the clutch, I'm sure we are all familiar of what a failing clutch smells like.
I therefore have been testing the car trying to repeat the symptoms. Fast acceleration in 1st and 2nd is no problem, jump to third and here we get what I thought could be clutch slip but not convinced. I have found that if I hold the throttle when this happens there is zero smell and seemed to just have no power. However, back off a tiny bit and the car takes off like a scolded cat. This has led me to suspect the plugs are blowing out when the boost gets to high. A quick check of the plugs while at my son's for its MOT recently confirmed that the plugs are well past their best, or to use my son's words, these plugs are dead.
I so today I replaced them with my prefered choice of NGK Iridium IX 7's.
A few things while doing this, first when removing one of the hoses for access to No. 3 plug lead the small tube came out of the manifold, I wonder how long that's been leaking if indeed it was?
No big deal, a quick clean of tube and manifold with IPA I reassembled using a Loctite retaining bonder, in this case, 640 which is a very fast setting type.
Pictures hopefully show this.
On inspecting the old plugs they clearly are dead, well the top one from No.1 isn't too bad but 2,3 and 4 have large deposits around the probe. The good thing is that all 4 were dry and of a good colour, no sign of nasty oil.
All back together now, I'll have to leave the road test for better weather, can't test properly with wet roads.
I'll update if this solves the issue or not soon.

Son No. 2 has a friend who has his own business but I don't know this guy and am not sure about using him. So a bit of a quandary right now.
