A Christian parent has threatened her child's school with legal action after it organised a pride parade which she claimed promoted LGBT lifestyles.

Heavers Farm Primary School in London held a parade earlier this year in which encouraged children to celebrate “what makes them proud of themselves and their family”.

The primary school was forced to cancel family invites after a group of parents threatened to stage a protest.

Izoduwa Adhedo claimed the event went "against our Christian beliefs" and was an attempt at "indoctrination".

Christian Concern, a conservative group, is supporting her as she considers legal action.

Ms Adhedo, whose son attends the school, was due to meet school governors to make a formal complaint on Tuesday.

In a statement, she said: “After I complained about my young child being forced to take place in an event that goes against our Christian beliefs, the school’s attitude towards me changed completely. I know other parents who are afraid to speak up because of how the school has treated me.

“It was like being bullied. They stopped treating me like any other parent but were antagonistic towards me. I believe that they retaliated against me by unreasonably excluding me from the premises, victimising my child and not taking my safeguarding concerns seriously.

“I wasn’t even trying to stop the Pride event. I just wanted my child to receive an education, rather than indoctrination.”

Susan Papas, the headteacher at the school, told The Guardian: “Equality is a thread that goes through our curriculum. We’ve done projects on black history month, disability and women’s history.
