PRIVATE schools across Scotland are facing a new challenge to their charitable status.

The Scottish Parliament's public petitions committee is seeking evidence from teaching unions, councils and the independent sector.

The move follows the lodging of a petition with the committee calling for private schools to be stripped of their charitable status - awarded to them because they are a provider of education.

Petitioner Ashley Husband Powton told the committee charitable status allowed private schools to claim an 80 per cent discount on non-domestic rates, pay no corporation tax and claim gift aid on tax donations, while state schools pay a full tax liability.

This, she said, allowed Fettes College in Edinburgh to pay just £41,828 tax, while nearby Wester Hailes school, where two-fifths of pupils receive free school meals, pays its full tax liability of £261,873.

"To put this in context, the average pay in Scotland is £26,472.

"So, it is undeniable that for the vast majority of the Scottish population the privilege of a private education is far outwith their reach. It's impossible to argue that access to these schools is not unduly restrictive."
