Data shows UK labour market weakened in December
Jan 20 (Reuters) - UK stocks slipped on Tuesday, swept up in a global risk-off mode after U.S. President Donald Trump vowed to slap tariffs on European nations until the U.S. is allowed to buy Greenland.
The blue-chip FTSE 100 .FTSE was down 1.1% as of 1042 GMT, set for its biggest one-day drop since November 18. The domestically focused mid-cap index .FTMC dropped 1%. Both indexes were set for their steepest intraday fall since mid-November.
Trump has threatened to impose an additional 10% tariffs on imports from Denmark, Norway, Sweden and Britain, among others from February 1, unless the United States is allowed to buy Greenland, heightening volatility across global markets.
"What happens next for financial markets will ultimately depend on Trump's actions in the coming days. For now, he is sticking to his guns and said that there is 'no going back' on his Greenland pledge," said Kathleen Brooks, research director at XTB.
Brooks said Trump's comments over Greenland at Davos this week will be critical.
Davos is hosting the World Economic Forum, with world leaders, policymakers and corporate executives scheduled to deliver speeches.
