Where is the water heater drain valve?

Hi everyone, in April we purchased a 2010 Autosleeper Lancashire, and very happy with it we are. So this is its first winter with us, however I am unable to locate the drain valve for the hot water tank! 

We had a Swift Sundance motorhome a few years ago and as soon as you lifted the panel out the wardrobe floor the drain valve was almost the first thing you saw! Not so the AS Lancashire, as I'm faced with a wild jumble of electrical wires, water pipes and heater ducts. I have spotted the water tank, so I assume I'm in the right area. So I've now spent some considerable time poking around with various combinations of torches and telescopic mirrors trying to locate said drain valve, all to no avail. I'm now beginning to wonder if its positioned at some remote location miles away from the water tank! (Silly, I know).

Anyone out there with a similar machine able to advise? Please?

Thank you Ploughlin! Now found and opened. On reflection, I suppose that is pretty close to the water tank, I should have thought of looking there.... Cheers!
