Could a Lincolnshire school be home to the most twins in the country?
De Aston School in Market Rasen has five sets of identical twins and one set of non-identical in one year group, with another six sets of twins in a different year.
Head teacher Ellenor Beighton said it was "probably down to something in the water".
