Britain's top share index rose on Thursday, with investors' risk appetite rising after minutes of the U.S. central bank's latest policy meeting suggested it would be more cautious in raising rates than expected, Reuters reported. The blue-chip FTSE 100 index rose 0.8 percent to 6,685.37 points by 0800 GMT after gaining 0.7 percent in the previous session. The index is still down nearly 1 percent this year after surging 14 percent in 2013. Cyclical shares were broadly in demand, with the UK banking index rising 1.1 percent and miners up 0.9 percent as the Federal Reserve minutes prompted a shift in expectations of when U.S. interest rates will start to rise. The FTSE 100 was also supported by strong gains recorded by some individual shares following their announcements.
