Interests and Hobbies

I am a problem solver by nature and relish the challenge of applying legislation to different scenarios. Data Protection law is there to protect the man and woman in the street, not to prevent you doing business!

I am a petrol head and love to watch Formula 1 Grand Prix, my last outing being to Spa-Francorchamps in the beautiful Ardennes region of Belgium. I seem to spend a lot of time honing my DIY skills and love to buy new power tools! Other than that, my family are my hobby and interest!
