It's only December 1 but it must feel like Christmas already for two Premium Bonds holders in Cornwall and Kent as they've won this month's £1 million jackpot.

This month the Premium Bonds prize fund has got even better, after NS&I, which runs Premium Bonds, passed on the Bank of England's Base Rate rise to bondholders. What this means is the odds of winning a big prize have improved and the number of big prizes has increased, with four prizes of £100,000 and 10 prizes of £50,000 now up for grabs.

Check our table below to see if one of you’ve scooped one of the big prizes in December.

Good luck!
