Following my diagnosis on Friday of three slipped discs, compounding the motor racing injury from my crash in May, together with the pain I have been experiencing over the weekend after racing at Silverstone, my Doctors have banned me from flying or travelling.  I really apologise to everyone who was hoping to see me on my South African tour and am hugely disappointed to have to cancel at such short notice. My publishers will reschedule and I look forward to a trip in the future.
