LONDON — Official figures show that Britain’s economy contracted more than first estimated, shrinking by 0.3 percent in the first quarter from the previous three month period. The Office for National Statistics on Thursday revised its estimate from the 0.2 percent drop reported initially. The expectation in the markets was the decline would be unrevised. This was the second consecutive quarter of negative growth and puts Britain back in recession — officially defined as two straight quarters of negative growth. In the last three months of 2011, the British economy contracted by a quarterly rate of 0.2 percent. The British economy has now returned to a technical recession, defined as two successive quarters of contraction, after shrinking by 0.3 percent in the final three months of 2011. — AFP
