A Suffolk man won £400,000 on a national radio show. 

Richard, 47, won the Greatest Hits Radio Win Happy competition while stuck in traffic on the M25 with his family. 

The Bury St Edmunds man was with his family on the way to Surrey to visit his brother. 

Presenter, Gemma Atkinson called Richard to tell him he had won the £400,000.

When answering the call the 47-year-old when answering said: "Oh blimey, wow I don't know what to say to that. It's fantastic.

"We entered religiously for the last couple of weeks because you never know when you might get picked." 

Atkinson asked him what he is spending the money on and he said "paying off the mortgage, do the house up and maybe a new car." 

The tax free money is the biggest ever cash prize on Greatest Hits Radio and the winner only needed to answer the call to win. 

The number for the competition is picked at random.
