What can I say? I'd look after my immediate family before anyone else:
1. pay off debt (house mortgage)
2. get planned renovation done (plans already at the council but really don't have the money to do it yet...)
3. invest about half of it
4. give money to siblings and parents (mine and my wife). What they did with it is their business. Exactly how much would depend on exactly how much we won.
5. stick the rest into the bank where we could spend it at our leisure.
The bonus of paying off the debt is it would make my income something we can 100% use for ourselves.
Pure speculation, as I don't buy lottery tickets
