Britain's youngest Mega Lottery winner has been charged with killing a pensioner in a car crash.

Matt Topham, 31, won £45million on the Euromillions in 2012.

He was behind the wheel of a BMW when he allegedly smashed into the Ford Fiesta carrying Mary Jane Regler, 75, on Christmas Day 2019 in North Cockerington, Lincolnshire.

Mary Jane Regler died and her husband, Rodney, 78, who was driving, was seriously injured.

Mr Topham was charged in September with causing death by dangerous driving and causing serious injury as a result of dangerous driving, the Mirror reports.

The Lotto winner, who is a dad-of-three, appeared via video-link at Lincoln Crown Court on Thursday, November 12.

Mary Jane Regler tragically died following the crash

Mary, who used the name Jane, lived with her husband in North Cockerington.

She was taken to Grimsby Hospital after the collision but tragically died from her injuries.

In an obituary in her local newspaper in February, her family said she had been "tragically taken" from them.

They described her as a "much-loved wife, mum, nan and friend who will be sadly missed by all that knew her".

Her daughter-in-law posted on Facebook after her death: "The sudden death of someone you love is like being punched in the face.

"It takes a while to register what's actually happened before it properly starts to hurt.

"The bruises and the lasting effects, both physically and psychologically are going to be with you forever."

Hundreds of mourners wearing bright colours turned out for her funeral at Alford Crematorium.

Topham is said to be a fan of fast cars

Topham, who won the jackpot with his supermarket worker wife Casey, will next appear in court on December 18.

He is due to stand trial next March.

The couple went public with their EuroMillions win in February 2012 and hit the headlines after planning to build a 'Teletubbies' mansion.

They have also splashed out on luxury cars, houses and holidays for family and friends.

It emerged last week that he had bought his mother-in-law a £600,000 petting zoo.
