The Mayor, Boris Johnson, will face tough questions from London Assembly members over plans to close more than 30 fire stations.
The budget for the London Fire and Emergency Planning Authority (LFEPA) is being cut by £64.5million over the next two years.
Labour members say to meet the funding gap, 31 stations and 36 fire appliances are earmarked to be cut. The list of closures has been revealed in a report that will be presented to LFEPA this week.
The Fire Brigades Union has described the planned closures as "completely unacceptable" and say they believe public safety will be affected.
