THE newly merged British banking group Lloyds TSB yesterday said it was still on target to achieve savings of £350 million sterling a year by the end of the century as it revealed its maiden interim results had matched City forecasts. The group, formed out of the merger of Lloyds Bank and TSB in December, made £1.14 billion in the six months to June 30th, a 12 per cent increase on the £1.02 million made by Lloyds Bank in the first half of 1995.
