LONDON, Jan 19 (Reuters) - Bank of England Governor Andrew Bailey said on Thursday that financial markets now expected energy prices to take longer to fall than just a few months ago, which risked further embedding price pressures. Greater tension between Russia and Ukraine were also a problem. "That is a very great concern," Bailey told lawmakers from parliament"s Treasury Committee. "If you think about the relationship between transitory and these second round effects that can make it much longer - that again is a source of pressure in this story, which is a concern."
