The London Fire and Emergency Planning Authority (LFEPA) is meeting today to decide its next step in its dispute with Boris Johnson over fire station closures.
The Mayor wants to close 12 fire stations and get rid of 18 fire engines, a plan that LFEPA voted against at their last meeting.
Boris Johnson has said the Authority could face legal action, and he had given them until today to back down.
The Authority has three options: they can continue to defy the Mayor and face a judicial review, accept the plans and see services cut or push for an amended public consultation process.
The Mayor's Office has said it's essential that the fire service continues to modernise. The service needs to save £45m over the next two years.
