Chipotle founder Steve Ells steps down as chairman

March 6 (Reuters) - Chipotle Mexican Grill said on Friday founder Steve Ells has stepped down as executive chairman and director, handing over the role to Chief Executive Officer Brian Niccol.

The restaurant chain said it would reduce the size of its board to seven from 10, as two directors, Matthew Paull and Paul Cappuccio, will not stand for re-election. (Reporting by Nivedita Balu in Bengaluru; Editing by Arun Koyyur)
