Ghana's gross domestic product growth including oil will stand at 4.1 percent in 2015, the statistical service said in an estimate on Friday based on growth in the first half of the year. 

The government earlier adjusted its growth forecast to 3.5 percent.

Ghana had for years one of the strongest economies in sub-Saharan Africa but growth has slowed sharply in the last two years due to a fiscal crisis and lower global commodity prices, which have affected its gold, cocoa and oil exports.
