The London markets and sterling stumbled on the back of a slew of poor economic data and caution over the potential for harsher travel restrictions across Europe.

January's early PMI (purchasing manager's index) figures came in significantly below economist expectations after the latest lockdown hammered private sector activity.

Meanwhile, new figures from the Office for National Statistics (ONS) showed that retail sales in 2020 fell at the fastest rate in 23 years, while government borrowing rose to £34.1 billion last month.

The FTSE 100 closed 20.35 points, or 0.3% lower, at 6,695.07 at the close of play on Friday. "It is a broad-based sell off, as fears that England's lockdown might last until summer has impacted most sectors," said David Madden, market analyst at CMC Markets UK.

"There are concerns the EU might shut internal borders and there has been chatter the bloc might ban travellers from the UK.

"Even though none of these measures have been confirmed, the very mention of them has soured sentiment in equities."

Elsewhere in Europe, sentiment was also weighed down by PMI data showing regional declines, with the French CAC particularly impacted by a worse-than-expected performance for its services sector.

The German Dax was 0.36% lower and the French Cac moved 0.56% lower.

Across the Atlantic, markets cooled as the S&P and Nasdaq recoiled from Thursday's record highs are traders were content to trim their exposure to stocks following the latest bullish run.

Sterling was particularly weak in the face of the UK's poor day for economic data, with the below par set of PMI figures sparking a sell off on Friday morning.

The pound decreased by 0.38% versus the US dollar to 1.368 and was down 0.47% against the euro at 1.123.
