  The majority of fast radio bursts (FRBs) are poorly localised, hindering
their potential scientific yield as galactic, intergalactic, and cosmological
probes. LOFT-e, a digital backend for the U.K.'s e-MERLIN seven-telescope
interferometer will provide commensal search and real-time detection of FRBs,
taking full advantage of its field of view (FoV), sensitivity, and observation
time. Upon burst detection, LOFT-e will store raw data offline, enabling the
sub-arcsecond localisation provided by e-MERLIN and expanding the pool of
localised FRBs. The high-time resolution backend will additionally introduce
pulsar observing capabilities to e-MERLIN.
