Blue chip shares held on to the gains made during its record close, buoyed by Lloyds Banking Group returning to the private sector eight years after it was saved by the taxpayer.
Lloyds Bank said the government will see a return of £21.2bn on its investment, after it pumped in £20.3bn at the height of the financial crisis for a 43% stake in the business.
The FTSE 100 Index slipped 0.8 points to 7521.3 in afternoon trading, after top flight shares closed at an all-time high of 7522 in the previous session, buoyed by rises among a broad range of consumer-focused companies. The FTSE 250 Index fell 23.4 19852.5.
IG chief market analyst at Chris Beauchamp said: "The government made a profit on its Lloyds investment, and with dividends looking healthy it seems that private investors are convinced they can prosper too with the bank."
