Ok, a big thankyou to all who responded and it has helped me greatly, I have been practicing for several hours now and I consider the problem to be solved.
I used to design, build and install computer systems and we had a saying in the workplace and that was:
Most problems originate between the chair and the keyboard, and I believe I now fit into this description......
I considered and implemented all suggestions here and I ended up with:
More brake dead zone
Less brake saturation
Adjust steering angle
End result surprised me greatly, instead of barreling down the straight at breakneck speed and then standing on the brakes and trying to round the corner, the brakes are now less sensitive and I have to brake earlier. It took a bit of getting used to but the end result is more corner speed, a smoother transition through the corner and earlier on the throttle and more consistent lap times. I have picked up nearly a second a lap on initial testing laps
SO THANK YOU ALL
