Which is the better investment strategy? premium bonds or national lottery?

Say i had £2,000 to invest. as part of my portfolio (which includes a range of investment types of differing risk and return), i want a low risk investment, which has the potential for large returns, and i am prepared to take the hit on inflation as a trade-off. which is the best strategy across the following two criteria: - best average return from the strategy - likelihood of making £1million from the strategy strategy 1: invest the £2,000 in premium bonds. strategy 2: invest the £2,000 in a bank account (say 5.5% interest rate) and spend the interest earned each month on national lotto tickets (about 2 per week).
Answer
In the scenario you give it has to be all in premium bonds because you get your stake money back, anything else would be a no brainer.
