London open: Footsie flat despite falls for BP, Weir and Fresnillo

- BP, Weir and Fresnillo provide some downward pressure- UK consumer confidence remains subdued- Markets await the Fed and ECBSome disappointing results from BP, Weir Group and Fresnillo were preventing gains for the Footsie on Tuesday morning; meanwhile, consumer confidence data in the UK showed that sentiment remained subdued in July.The GfK consumer confidence index was unchanged this month at -29, in line with consensus forecasts. Analysts at Barclays Capital said this morning: "Consumer confidence remains subdued and it has been at these low levels (between -29 and -33) for over a year now. Although inflation has fallen and the unemployment rate has edged down, we think the uncertainty about the economic outlook, the continued austerity measures and weak earnings growth are likely to keep consumer sentiment at subdued levels in the near term."Investors were also showing caution following some strong gains the day before as markets hope for central bank action in the US and Europe this week. The Federal Reserve kicks off its two-day policy meeting today, while the European Central Bank (ECB) will reveal its decision on Thursday. Many are expecting the ECB to resume bond-buying after its President Mario Draghi said last week that the bank will do "whatever it takes to preserve the euro...and believe me, it will be big enough".FTSE 100: Heavy falls from BP, Weir and Fresnillo early onWeaker oil and gas prices and a cut in output due to an extensive maintenance programme hit BP's profits hard in the second quarter.
