Growth in the UK's key services sector has hit its lowest level since July 2016, prompting fears of stagnation.
The purchasing managers' index (PMI) from IHS Markit/CIPS sank to 50.4 in November, down from 52.2 in October. A figure above 50 indicates expansion.
"The survey results suggest that the pace of economic growth has stalled," said Chris Williamson, chief business economist at IHS Markit.
The services sector accounts for about 80% of the UK economy.
