Tube strike causes disruption
Transport for London says services are running on virtually all tube lines as London copes with the fourth tube strike since September.
There is disruption on most lines.
The row involves jobs going at ticket offices but tube managers deny union claims safety is at risk.
The strike finishes at 6.30pm but don't expect things to be back to normal until Tuesday morning.
