The headteacher of a £31,000-a-year private school tipped to be attended by Prince George has urged parents to spend more quality time with their children.

Adam Pettitt, head of prestigious fee-paying Highgate School in north London, urged families to ensure their offspring have more time away from mobile phones.

His school has attracted celebrity parents including Jude Law, Gwyneth Paltrow and Dame Emma Thompson.

And it was recently toured by the Princess of Wales, prompting speculation she and husband Prince William could be considering the school for eldest child George, 11.

Highgate School, founded 460 years ago, is a co-educational day school for pupils aged between four and 18 - with annual fees for its secondary school currently charged at £31,575 plus obligatory lunch fees bringing the total to £32,640.
