Labour is holding its annual party conference in Brighton this year, and it's all going smoothly, apart from one issue – quite a few people are angry at the choice of backdrop for the main speeches.
Quite a few people on Twitter are furious because when they look at the backdrop, all they see is a mosque.
It's really concerning them.
Quite a few of the accounts pledge their support for far-right anti-Islam parties and seem genuinely concerned.
The thing is, it's not a place of Islamic worship, it's Brighton Pavilion.
Brighton Pavilion is a royal palace built for George IV as his seaside retreat in the late 18th century. It was later decorated in an Indian-influenced style by the architect John Nash.
It is not, nor has it ever been, a mosque.
