Mr Smith added: 'We have had a lot of positive comments from parents as well about our uniform.'We are not denying anyone the right to wear a skirt, we are saying that is not part of the school uniform.
I'm not imposing anything on what they do out of school in their free time.'He added that there was no consultation because current students were not affected by the change.
Schools are under political pressure to cater for trans pupils, with many installing gender neutral toilets and also allowing youngsters to wear the uniform of either gender.
However, it is understood Priory School is one of the first to adopt an entirely gender neutral uniform for all pupils.
Parents are outraged after a secondary school once attended by Piers Morgan banned girls from wearing skirts as part of a new gender neutral uniform policy.
