All nine syndicate members work at Worksop College Preparatory School Ranby House and are known as "the Ranby Revellers". They have been working together—and playing the lottery together—for 12 years, but apart from the occasional £10 this is their only big win.
None of the ladies have any definite plans for their share of the money, but they say they may help out their families.
"It's so nice to have won it together after being friends for so long," said leading Ranby Reveller Irene Grant.
