A bitter row between a Birmingham primary school and its mostly Muslim parents over the teaching of LGBT equality has led to street protests and the suspension of the lessons. The Guardian’s Nazia Parveen traces the origins of the dispute and where it has led. Plus: Hannah Devlin on the first ever image of the silhouette of a black hole

A row over the teaching of LGBT equality at Parkfield community school in Birmingham has resulted in lessons being suspended and protests spreading across the city and into other areas.

This week the education secretary, Damian Hinds, said it was right that parents were consulted and involved in developing how schools deliver relationships education, but insisted “what is taught, and how, is ultimately a decision for the school”.

The Guardian’s Nazia Parveen tells Anushka Asthana how after four years of good relations with parents – 98% of whom are Muslim – Parkfield school became a battleground that also drew in activists not directly connected with the school.

Also today: astronomers have captured the first ever image of the silhouette of a black hole. The Guardian’s science correspondent, Hannah Devlin, explains why it is such an exciting breakthrough.
