We have discovered a new, near-equal-mass, eclipsing M dwarf binary from the Next Generation Transit Survey. This system is only one of three field-age (>1 Gyr), late M dwarf eclipsing binaries known, and has a period of 1.74774 d, similar to that of CM Dra and KOI126. Modelling of the eclipses and radial velocities shows that the component masses areMpri=M⊙,Msec=M⊙; and the radii areRpri=R⊙,Rsec=R⊙. The effective temperatures areK andK, consistent with M5 dwarfs and broadly consistent with main-sequence models. This pair represents a valuable addition that can be used to constrain the mass–radius relationship at the low-mass end of the stellar sequence.
