The London Underground saw significant disruption this morning with service suspensions affecting a number of lines.
The Circle line was completely suspended due to a points failure at High Street Kensington.
The same issue halted service on the District line between Tower Hill and Ealing Broadway, with severe delays on other sections.
Lines have now reopened, though the Circle line is still subject to minor delays.
Meanwhile, there was no service between Charing Cross and Camden Town northbound on the Northern line because of signal failure at Warren Street. This has also now cleared.
