A woman living in Wiltshire who bought a Premium Bond back in July 2003 has won one of this month’s £1million jackpots.

The other winner is a man from Suffolk who bought his winning Bond in September 2006.

The female winner actually holds £12,725-worth of Premium Bonds while the man has £ 38,981 invested in the Government-backed prize draw.

More than £60m was paid out to around 2million prizewinners this month, with the bulk receiving £25, although there were also four prizes of what could be a life-changing £100,000, 10 prizes of £50,000, 17 of £25,000 and 44 of £10,000.

The odds of winning any prize in the monthly draw are currently 26,000 to 1, although the odds of winning a jackpot are much higher.

All prizes are paid tax-free although anyone who doesn't end up a winner will only get their cash returned with no interest added.

Meanwhile there remain more than a million unclaimed Premium Bond prizes worth collectively around £48m.

There is no time limit for claiming prizes so even if you won decades ago - the first draw was June 1957 – you money will be waiting for you.

There’s a free NS&I Premium Bonds prize checker app which lets you check if you’ve won a prize in the past six months.
