Tuna is apparently off the menu at a Kingston junior school - following a four month campaign by one of its students.

Freya Greatwood, 11, convinced friends at St Paul's Junior School in Princes Road to boycott the school's tuna bake lunchtime meal after discovering the fish was in decline.

The aspiring marine biologist said: "I have always been into the sea but I didn’t know that there weren’t that many tunas.

"I looked it up and found out how endangered they are.

"I told my friends and we all stopped eating it. They all supported me."

To kick-start her campaign Freya wrote a letter to the headteacher at neighbouring Alexandra Infant School before writing to her own headteacher, Kevin Edmonds.

She said: "I think Mr Edmonds kind of just gave up on this one because I would have got the whole school not to eat tuna."

Proud dad Marcus Greatwood, who works as a free diver, said: "Nobody was taking the tuna bake so they had to put out extra sandwiches.

"I am really proud of her. She had been fighting for it and she saw it all the way through."

Freya, of New Road, Kingston, said: "I feel very triumphant.

"I really want to open the secrets out there in the water world and fight off illegal whalers."

St Paul’s Junior School said they did not want to comment on the change in menu.

Freya said she still enjoys school dinners, with cheesy pasta bakes being a favourite.

She said: "I still like sausages, turkey and cheesy pasta. I don’t eat fish because I don’t know how it has been caught.

"My middle name is Dolphine but I don’t really have a favourite sea creature because I like them all."

The youngster added her inspiration has been Canadian environmental activist Paul Watson who focuses on marine conservation.

She said: "Paul Watson said ‘If the sea dies, then we die’. That really makes sense to me. I didn’t realise he would be my inspiration at the time."
