- Rajoy denies Spanish bailout request- Chinese data disappoints- Tesco and Sainsbury's fall after updates- FirstGroup sinks after West Coast failureStocks in the UK slipped in early trading on Wednesday as concerns about a Spanish bailout and weak economic data from China spooked investors.Spanish Prime Minister Mariano Rajoy yesterday denied claims that his country is looking to request a bailout this weekend. He said that the country had no immediate plans to ask for aid.When asked about a report in Reuters on Monday, Rajoy said: "If a news agency reports that we'll ask for aid this weekend, there can only be two explanations; that the agency is right, and knows more than I do, which is possible, or that they are not right."But, if it helps, and you accept that what I say is more important than this leak, I say no (we won't ask for aid this weekend.)"Market analyst Craig Erlam from Alpari said this morning: "The comments are unlikely to have to have a major impact on the markets as long as Rajoy doesn't delay making the request for too long. It is thought that he is holding out until after the regional elections on 21 October, a similar move to what we saw earlier this year."In economic data today, China's non-manufacturing purchasing managers' index (PMI) fell from 56.3 to 53.7 in September, according to the National Bureau of Statistics and China Federation of Logistics and Purchasing.Meanwhile, China's consumer sentiment index fell from 90.4 to 89.3 last month, its lowest level since December, according to Deutsche Boerse's MNI.FTSE 100: Retailers disappoint early onSupermarket chains Tesco and Sainsbury's failed to impress with their updates this morning, with both providing a drag on the Footsie in the opening hour.Global retailer Tesco fell despite seeing a return to like-for-like (LFL) sales growth in the second quarter.
