Japanese financial newspaper Nikkei is buying Financial Times from U.K. publishing group Pearson PLC PSON, -2.94% for 160 billion yen, or about $1.3 billion, Nikkei and Pearson said Thursday. Pearson earlier on Thursday confirmed it was in advanced talks over the possible sale of the British FT Group, which includes the Financial Times newspaper, but the potential buyer was not disclosed. Nikkei announced the agreement in an email to subscribers Thursday afternoon U.K. time. Pearson confirmed later in the day it has agreed to a cash deal worth £844 million.
