CND said 60,000 took part in the event
Jeremy Corbyn spoke and reminded the crowd, "I said if elected I would replace Trident with jobs that would retain the community's skills.
There were many young people present, as well as veterans of the anti-nuclear movement from previous decades
The £167 billion that will be wasted on Trident could be used for the NHS, education, welfare and action against climate change
The march was another sign of a mood of radicalisation in British society
Some unions joined the march
"Scrap Trident, no to Nato, fund the NHS not missiles"
Kate Hudson, general secretary of CND told the Trafalgar Square crowd, "I can honestly say that this is the largest anti-nuclear protest for a generation"
