A couple who scooped £1 million on the National Lottery have joined other winners to help out at the hospital that saved their son’s life.

Ceri and Paul Roscoe-Roberts, who won on the EuroMillions last November, joined 21 other National Lottery winners at Alder Hey Children’s Hospital in Liverpool on Tuesday to help out with some gardening on-site.

Mrs Roscoe-Roberts, 43, from Conwy, North Wales, said the hospital had previously saved the life of her youngest son, now 16, when his pushchair collapsed with him inside and she had to resuscitate him.

The mother-of-five said: “Without Alder Hey, my youngest would not be here today.

“The hospital does so much incredible work and I am truly honoured – thanks to my National Lottery win – to be back here today giving something back in terms of my time and contributing to a project which really will benefit thousands of people for many years to come.”

The group of winners, worth a combined total of £32 million, spent the day planting borders alongside a new walkway around the Alder Centre bereavement unit.

The hospital is currently undergoing multi-million-pound redevelopment to create a world-class healthcare campus, where all aspects of children’s health can be addressed in one dedicated space.

Patricia Gill from Warrington, who with husband John won £1 million on Euromillions in 2015, said: “It is wonderful to think we can play a part in such a major building project and at such a prestigious location – not only in the UK – but across Europe.

“Everyone knows about Alder Hey and the tremendous life-saving work that the hospital does and to be able to help to create an even better environment for children and their families, really is a true honour!”

Fiona Ashcroft, chief executive at Alder Hey Children’s Charity, said: “We have been extremely grateful to have the lottery winners on site – they have certainly done an excellent job and played a very important part in developing our Children’s Health Campus here at Alder Hey.”
