The decrease in the UK’s R rate, Government confirmation of when it will unveil the roadmap out of current lockdown measures and better-than-expected economic figures for the past quarter all pushed the FTSE higher.
Sterling also made gains as traders were positive about the rate of the UK’s economic recovery.
Earlier on Friday, the Office for National Statistics (ONS) confirmed the UK economy dodged a double-dip recession amid 1% growth in the final quarter of 2020, ahead of a 0.5% forecast.
The FTSE 100 closed 61.07 points, or 0.94%, higher at 6,589.79 at the close of play on Friday.
Connor Campbell, financial analyst at Spreadex, said: “With the UK’s R value dropping below one for the first time since last July, and the Government confirming they will issue their roadmap out of lockdown on February 22, the FTSE and pound swung positive on Friday afternoon.
“After spending most of February ranging between 6,500 and 6,550, the FTSE found itself slipping below the bottom end of that bracket earlier in the session, only for a reversal of fortunes to push it beyond 6,570.”
The pound also edged higher later in the day’s session, with sterling just a fraction off Wednesday’s 33-month peak against the dollar.
The pound increased by 0.31% versus the US dollar to 1.386 and was up 0.34% against the euro at 1.143.
Elsewhere in Europe, equity markets were far more mixed with the Dax crawling back into the green after spending most of the day at a loss.
The German Dax was 0.02% higher and the French Cac moved 0.6% higher.
In the US, the Dow Jones dipped on a conservative session as a lack of immediate progress on Joe Biden’s stimulus plan kept traders quiet.
In the UK, housebuilders including Bellway, Taylor Wimpey and Berkeley made modest gains after the Government extended the deadline for the Help to Buy scheme until the end of May.
