File photo dated 06/07/11 of children at school raising their hands to answer a question as a third of parents think school trips are unaffordable, while many others think the costs of uniforms and equipment are too high, a poll suggests. PRESS ASSOCIATIO Adver readers were split when discussing when schools should reopen to all children. During the third national lockdown, all schools have been closed and children have had to work from home. Only vulnerable children, children without internet access or children of key workers could continue going into school. Boris Johnson announced yesterday that schools would not be returning after the February half term but he is hoping they will reopen by March 8.
