Players are being offered the chance to win up to £25,000 as Wiltshire Air Ambulance builds on the success of its lottery draw.

The new Superdraw, launched on Monday, gives regular weekly lottery participants the added chance of winning the bigger sum for an extra £1 a week.

Its regular lottery, operated by the Air Ambulance Lottery Society, offers a weekly top prize of £1,000. Players for the Lottery and Superdraw must be 16 or over.

Wiltshire Air Ambulance’s head of events and charity services, Claire Kelly, said: “Our regular lottery has some 23,400 members, who between them raise more than £578,000 a year. We are extremely grateful to these people whose ongoing support is helping to secure the long-term future of our life-saving service.

“As we don’t receive any Government or National Lottery funding, we are totally reliant on the generosity and support of local people to keep us flying.

“The money raised from our lotteries provides regular, steady income which we can rely on, enabling us to plan ahead and ensure that we can continue to keep saving as many lives as possible.

“By introducing Superdraw, we hope that even more people will join our lotteries.

“Winning £25,000 really could change someone’s life – it could pay for a holiday of a lifetime, help you move home or buy a dream car.”

Wiltshire will have its own air ambulance from December, when its partnership with the police ends. It will have to increase its fundraising to £2.5 million a year.
