LONDON (AFX) - Bank of England governor Eddie George reiterated that the bank will have to tighten monetary policy if domestic demand does not moderate naturally. "If we feel that domestic demand is not moderating of its own accord, we will have to tighten (monetary policy)," he said, appearing before the Treasury Select Committee. However, he acknowledged that domestic consumption may indeed slow of its own accord. George said the UK's first-quarter GDP data may to be revised up slightly. He said he was "surprised" by the flat growth in the first quarter indicated by National Statistics data. "The numbers should not be disregarded but it did surprise us," he said, adding that "there are puzzles" about the figures citing the the trade and GDP deflators. "There are inconsistencies with the actual statistics and survey evidence from our own agents around the country," he said. "It is quite possible that the figure is revised and if so we expect it in a a positive way," George said, adding that he had expected a "marginally stronger" reading. However, he said the data has no implications for the BoE's econometric models. On the same issue, BoE deputy governor Mervyn King said he expects a "significant difference" between Q1 and Q2 GDP data, citing the recovery in overall survey evidence as well as in the manufacturing sector
