Freddie O'Keefe was born weighing 9lb 8oz

The drama was played out at the Asda store in Crawley, West Sussex, and ended with a baby boy being born.

Vicky O'Keefe's contractions began as she was walking down an aisle at the supermarket on Sunday afternoon.

The 21-year-old mother spent an hour in the first aid room, with a midwife, a paramedic and the store's first-aider all helping to deliver son Freddie.

Paramedic Duncan Jones said: "This was the lady's third child and although she obviously would have preferred to have been in hospital, she recognised things were happening too quickly for that."

Mr Jones said a healthy baby boy arrived within an hour.

After the birth, Ms O'Keefe and her new son were taken to the East Surrey Hospital for a check-up.

Asda spokeswoman Tracy Elliman said: "This is the first baby we have had born in our store since we opened two-and-a-half years ago.

"Kerry, our first-aider, did an excellent job and remained with the mum throughout.
