British Gas owner Centrica and utility group SSE were today extending losses after yesterday's proposal by Labour leader Ed Miliband to freeze energy bills if the party is voted back into power in 2015. The stock has now slipped below its 200-day moving average following three days of intense selling. Banking and financial stocks were also providing a drag, with Barclays, Aviva and RBS among the worst performers. However, insurer Admiral was bucking the trend, having registered decent gains throughout the day.Also on the up was TUI Travel after a strong high season this summer and heartening early bookings for winter holidays led the tour operator to hike its profit guidance for the full year. The company, which owns the Thomson and First Choice brands, said it was now confident of achieving at least 11% growth in underlying operating profits for the year to end-September. Compass Group was also a high riser after it said its expectations for the full year were unchanged with organic revenues set to have risen by just over four per cent and profit margins to have grown slightly. The catering giant said growth has been driven by new business wins and high client retention particularly in North America where organic revenue growth is expected to be around 7.5%.Tullow Oil also rose after announcing a new oil discovery in Northern Kenya. The group said results of drilling, wireline logs and samples of reservoir fluid indicate a potential net oil pay in the Auwerwer and Upper Lokone sandstone reservoirs of between 60 and 100 metres.FTSE 100 - RisersTUI Travel (TT.) 368.80p +3.48%Whitbread (WTB) 3,017.00p +2.72%Compass Group (CPG) 850.00p +2.41%G4S (GFS) 253.10p +1.85%Admiral Group (ADM) 1,250.00p +1.71%Sainsbury (J) (SBRY) 400.40p +1.52%BAE Systems (BA.) 468.20p +1.50%Schroders (SDR) 2,611.00p +1.48%Glencore Xstrata (GLEN) 344.45p +1.47%BHP Billiton (BLT) 1,885.50p +1.10%FTSE 100 - FallersCentrica (CNA) 367.90p -2.05%SSE (SSE) 1,462.00p -1.81%Barclays (BARC) 268.05p -1.81%Hargreaves Lansdown (HL.) 1,003.00p -0.89%Standard Chartered (STAN) 1,508.00p -0.85%Sports Direct International (SPD) 698.00p -0.85%BG Group (BG.) 1,195.00p -0.79%Persimmon (PSN) 1,107.00p -0.72%Legal & General Group (LGEN) 202.20p -0.69%Carnival (CCL) 2,092.00p -0.66%NR
