Strike action by firefighters has been called off after progress was made in a dispute over pensions.
The walkout was due to last from 6.30 to 11.30pm tomorrow and reduce the number of fire engines operating in London from 169 to just 27.
The Fire Brigades Union said it had been presented with a similar deal to one made by the Scottish Government, covering the retirement of firemen and women aged between 55 and 60.
