Blue chip stocks struggled for direction with traders heading into the weekend prepared to sit on their hands with little economic data to work off.

The FTSE 100 Index slipped 2.7 points to 6826.6, as the market reacted coolly to confirmation that UK economy grew by 0.5% in the third quarter, according to second estimates from the Office for National Statistics. The FTSE 250 Index fell 41.7 points to 17549.

IG chief market analyst Chris Beauchamp said it was "another slow day in London".

He added: "The only real piece of weighty news today was UK GDP, and even this didn't really cause much excitement, given the quarter-on-quarter figure was unchanged from the previous forecast."

The market was in no mood to take cues from Wall Street, which saw the Dow Jones industrial average top 19,000 for the first time in its 120-year history earlier this week, buoyed by President-elect Donald Trump $1trn (£804bn) infrastructure programme. The index closed at a record high of 19,023.87 on Tuesday (22 November).
