BT is higher after announcing that it is selling 5.5% of Indian IT Group Tech Mahindra to Mahindra & Mahindra. BT will still retain 24.4% of the IT company. The telecoms firm also benefited from an upbeat broker note from Exane BNP Paribas, which lifts its share price target for BT by 20% to 265p.There has been some profit-taking on some of the better performers from earlier in the week. Drug delivery technology developer Skyepharma had been boosted by news of the commencement in Japan of phase III trials for Flutiform, a fixed dose asthma treatment, which is administered via an inhaler. DRS has lost some of its gain following its statement earlier in the week that 2010 profit will be better than expected.
