Telecoms giant BT declined despite beating analysts forecasts with a solid rise in profits in its third quarter, as it announced a new 16-year "recovery plan" to pay down its expanding pension deficit, which now stands at £7bn. The company also revealed that it would upgrade its fibre network with large-scale pilots this summer of ultrafast broadband with G.fast. After an initial rise, British Airways and Iberia owner IAG fell into the red despite the news that Qatar Airways has bought a 9.99% stake in the company. While the Doha-based group said it may consider raising its interest in IAG over time, analysts at Liberum said a full takeover was "highly unlikely".Supermarket stocks were also under pressure, with Sainsbury and Morrison among the worst performers.Meanwhile, mining stocks were performing well with Fresnillo and Randgold advancing after heavy falls on Thursday as gold prices rebounded. Anglo American and BHP Billiton were also higher.RisersTullow Oil (TLW) 368.80p +5.10%Randgold Resources Ltd.
