LONDON (AP) — Britain's Treasury chief Rachel Reeves said Friday that she is “not satisfied” by official figures showing the British economy's rebound from recession slowed down sharply in the third quarter of the year, with most sectors stagnating. The Office for National Statistics said growth during the July to September period was just 0.1%. That was lower than the 0.5% recorded in the previous three-month period and below market expectations for 0.2%.
