The first winner, a woman from London, has £40,000 invested in Premium Bonds. The winning bond number (122EX485646) was bought in January 2007.

The second winner, a woman from Kent, becomes the 400th Premium Bond millionaire. Her winning bond (336ED173008) was bought just five months ago in July. She has just £5,300 invested in Premium Bonds.

Premium Bonds are offered by the government-backed National Savings & Investments (NS&I) and are the UK’s most popular savings product. Each £1 bond is entered into a monthly draw, with two lucky bondholders bagging £1m each. All Premium Bonds prizes are free of income and capital gains tax.

Jill Waters, retail director at NS&I, said: “Premium Bonds have made a real impact on people’s lives since the first prize draw in 1957, and while many good news stories never reach NS&I, Agent Million has endeavoured to deliver the news of a £1m jackpot win come rain or shine, leaving with warm tales of the positive impact on the winners’ lives.

“Premium Bonds have changed over time, however the core principles have not changed, offering tax-free returns and 100% security on every penny invested. Striving to offer customers what they want is also important, and we will soon be making it easier to buy and manage Premium Bonds, through our recent announcements to lower the minimum investment to £25, introduce gifting to a wider range of people, and the launch of a new app.”

In the December 2018 draw, close to 3.2 million prizes worth £91m will be paid out.
