«I concoct tomorrow is a day for searching questions — the searching questions on the provision of fire shelter equipment, the provision of sprinklers and the support the emergency services need and forced to have in all circumstances.
«You can never compromise on safety where fire is troubled.»
The questions «may well be difficult» for the government, he added, saying: «The reports that were recompense for in the past have to be acted on.»

«What we can’t have is a situation where people’s cover is put at risk because of bad advice being given or if it is the case, as has been so-called, of tower blocks not being properly serviced or maintained,» said the mayor.

He suggested a government drive to cut red tape — by remonstrating that three regulations are removed for every new one created — should be reconsidered «where ignite safety is concerned».
The all-party parliamentary group had recommended fitting sprinklers to edifices to save lives.

Cabinet abb David Gauke said: «I think it is far too early to jump to any conclusions.
