I would set up a charity that helps people in financial hardship out of it. Either by paying for them to train up in a profession or by putting them through a course on how to manage their money better. Or something of that nature. Maybe even have a branch that invests in people and their business ideas, help as many people reach their dreams as possible basically.
I would probably also buy a castle in Scotland. Then spend heaps on stocking the grounds up with animals, maybe even start a breeding programme for as many endangered British animals and birds as possible, with the aim of releasing them into the wild.
Family ~ well I would probably pay all of their mortgages off and give them a lump sum to live comfortably for a year.
For Chris and I, I would buy the most environmentally friendly 4x4 that money could buy. And all the best photography equipment I would need to set up my own studio would also be on my list. As well as a healthy eating cook and personal trainer to get us both 100% fit... I'd also (once fit) go hell for leather with IVF treatment.
I would also donate any savings, interest or profit earned on the money to the Norfolk coast. With specific instructions for it to be used to build the best sea defences the money can buy.
There is loads more I would do. But I have a feeling there wouldn't be much, if anything left of that little lot above
