Firefighters are to hold a further series of strikes in protest at government plans to increase their retirement age.
The Fire Brigades Union says the proposed changes mean those members who are unable to meet physical fitness requirements until the age of 60 would risk being sacked.
It also claims firefighters who opt for early retirement would be subject to “unacceptably high” reductions in their pension.
Firefighters have already held a series of strikes in protest at the proposals.
The latest rounds of strikes will see FBU members walk out between 12pm-2pm and 22:59-23:59 for eight days between Saturday 9 August and Saturday 16 August.
As with past strikes, the London Fire Brigade will use hire contractors to provide reduced fire cover during the walkouts.
Earlier this month Mayor Boris Johnson ordered the capital’s fire authority to consider withholding pay for entire shifts where firefighters failed to work some of their scheduled hours.
