I'm confident my "Water in Foot Well" problem is now sorted, and detail below what i did.
I started the car, set the A/C to 16 Deg, switched it on then set the fan to maximum speed and left the car to tick over. After about half an hour i had a small puddle of water on the floor beneath the car which then indicated where the drain point for the A/C condensate was.
I then jacked the front of the car, crawled under and found the outlet drain on the R/H side wall of the gearbox/prop shaft tunnel next to the gearbox and as you predicted it was made of rubber (i expected to find two drains but on my car i only had one). Small drips of water were emerging and dripping on the floor/my body every 2 seconds, but when i reached up and squeezed the rubber i was immediately drenched in about 12 plus litres of water.....that was my second shower of the day!
When i inspected the outlet of the drain found that the rubber flap (the shape of a birds beak) which was supposed to stop dirt entering and allow water to escape had not been formed properly ie:- only about a quarter of it was slit/free of the rest of the rubber of the drain and allowing the water to escape. I then proceeded to release the rest of the flap.
I have just come back from a 30 mile drive with the A/C on 16 Deg and max fan speed and thankfully no water has dripped onto the passenger foot well.....Job Done....until the next one?
Thanks again Dave for your support and help.
