The Financial Times has made further changes to its US bureau in New York, NY and Washington, DC. On top of the changes reported in recent weeks:

Robin Wigglesworth has been appointed US markets editor, based in New York. He will oversee the FT's coverage of US stocks, bonds, commodities, foreign exchange, derivatives and asset management. Wigglesworth is currently deputy head of fastFT.

James Fontanella-Khan has been appointed US M&A correspondent. He was previously a Lex writer and continues to be based in New York.

From February 2015, Ben McLannahan will be US financial correspondent. He will be relocating from Japan, where he is currently a Tokyo correspondent covering markets and economics.
