A 29-year-old man has become the youngest grandfather in Britain after his 14-year-old daughter gave birth, a media report said.

Shem Davies - of Bridgend, Wales - was also 14 when he became a father for the first time, The Sun reported.

His schoolgirl daughter Tia now has had a girl before her 15th birthday, it said.

Davies - who split with Tia's mother Kelly three months after she was born - said he was 'absolutely delighted' at the news.

Davies was 'shocked' when his daughter told him she was pregnant by her 15-year-old boyfriend.

He also has a nine-month-old son with new girlfriend Robyn Thomas.
