A trader said Didata is "the talk of the day" following news that Japan's Nippon Telegraph and Telephone Corporation (NTT), one of the largest global telecommunications service providers, has made a £2.1 billion bid to acquire the group.
The trader said the rest of the local equities showed a mixed performance, with investors waiting for more US earnings results and economic data.
