UPDATE 1-BT quarterly profit dragged down by Global Services unit

(Adds details on additions, CEO quote)

LONDON, Nov 2 (Reuters) - BT Group reported a 4 percent drop in second-quarter adjusted earnings, dragged down by ongoing problems at its Global Services unit, higher pension costs and sports rights.

Britain's biggest telecoms firm reported adjusted core earnings of 1.81 billion pounds for the three months to end-September, slightly ahead of forecasts, on revenue down 2 percent to 5.95 billion pounds.

The company said it was taking "robust action" to improve the performance of Global Services, which has been hit by a slowdown in international corporate work. The problems in the division offset growth in its EE mobile business.

Chief Executive Gavin Patterson, however, said the group was maintaining its outlook for the full-year and its progressive dividend policy.

"Our first half results are in line with our expectations as encouraging results in our consumer facing lines of business, notably EE, helped offset ongoing challenges in our enterprise divisions, in particular Global Services," he said.

The company said it added 279,000 contract mobile customers in the quarter, in line with the same quarter a year earlier, and 179,000 fast fibre broadband connections.

The total number of fibre connections on its Openreach network, which supplies connections for other providers as well as BT, rose 505,000 to reach a total of 8.6 million. (Reporting by Paul Sandle; editing by Kate Holton)
