Parents have refused to back down in their battle with school governors over a new uniform policy.

They have pledged to send their children in the blazers of their choice, rather than buy them from the school supplier, Andrew Firth, in North Street, Keighley.

A row blew up after blazers were introduced by Oakbank School in Keighley, despite a poll among parents coming out in favour of sweatshirts.

The campaign to shop around has been led by Mandy and John Hawley, of Exley Road, Keighley, whose son Jules will start at Oakbank on Monday.

He will not be wearing the set blazer and integral badge demanded by the school. Instead, he will wear a Marks & Spencer blazer.

Oakbank headteacher John Roberts and his governors have refused to change the policy to allow parents to buy blazers elsewhere and stitch on the badge.

Mrs Hawley said: "This is all over a £1.99 badge. If my son goes without the right blazer he will be put on detention. If he is on detention five times, he will be sent home.

"I think it is very hurtful. He is only an 11-year-old. When he goes, he will look absolutely smart.

"I have bought everything else they require because I didn't want to affect my son any further. This is about what parents feel and the school, not the children."

Despite the campaign, Andrew Firth said over two thirds of the school blazers it had in stock had been bought or ordered already.

"Nine hundred were required and a total of 600-plus have gone out or been ordered. This is about what we would expect. It is the same this year as any other," he said. His shop is opening seven days a week to cope with demand.

In a letter to Mrs Hawley, Mr Roberts said that if some people were allowed to defy the rules it would encourage lack of discipline and undermine the school authority.

Mr Roberts added: "Uniform is part of school discipline. If that discipline is defied, sanctions must be applied. Otherwise it is simply not fair to all those who have complied with the requirements."

He reminded parents that new government powers were expected which would allow heads to exclude children who persistently disobey uniform regulations.

Another parent, Christine Meeking, whose daughter will attend Oakbank, has also bought an M&S blazer. She said: "All we want is to be able to buy a badge which we could stick on the blazer. I don't want her attending school and being in trouble for a stand we are taking."

Mr Roberts has been invited to a public meeting at 7.30pm on Thursday at 88 Exley Road, Keighley, the home of Mr and Mrs Hawley.
