In a statement London Underground said that they had deferred the planned September 12th launch to allow for the successful conclusion of talks with transport unions and to prevent any further strike action.
There was transport disruption in London on Tuesday morning as the suspension of the Jubilee line led to overcrowding on many routes - Bank station was temporarily closed as a result.
While planned strike action for this week has been called off, Tube workers plan to walk out again on September 8th and 9th.
The property advisory firm said in a report released on Monday that tax changes, such as a rise in stamp duty on homes worth over £1.1 million, had contributed to a slowing in demand for property in sought after areas of London.
Average annual growth of home values in London's 13 'prime central' districts was 2 percent in the twelve months to July 2015, compared to growth of 7.9 percent for the previous annual period.
