An eight-month pregnant 66-year-old businesswoman, Elizabeth Adeney, is on her way to become the Britain’s oldest mom.

The baby will be Adeney’s first and the pregnancy was conceived using donor eggs and sperm, which has raised debate over the ethics of helping a woman her age conceive.

Currently, Britain's oldest mother is Dr Patricia Rashbrook, a psychiatrist who used a donated egg from Russia to birth to her son Jude in 2006, when she was 62 years old.

Adeney told the Sunday Mirror: It doesn't interest me that I'm going to be the oldest mum in the country. It's not my physical age that's important - it's how I feel inside.

The Managing Director of a Mildenhall, Suffolk-based firm, - which produces plastic and textile products - Adeney still works full-time, and lives in a £400,000 home in nearby Newmarket.
