Conservative Gareth Bacon accused Labour's Andrew Dismore of being "alarmist".
Bacon also asked if the government had indicated more money might be available for the fire service.
Boris Johnson said: "There is no such indication".
The Green Party also expressed its concern over the fire service.

There is no definitive list. This is all for discussion by LFEPA.
What matters to London is the threat of fire continues to diminish and the fire brigade should get there fast.
