Circumbinary planets, those which orbit both stars of a binary system, challenge our understanding of planet formation and orbital evolution. Planet formation around binary stars was thought to be difficult, and therefore these circumbinary planets were confined to the realm of science-fiction. Yet during its lifetime, Kepler discovered several of these objects. Since the discovery of Kepler-16b in 2011, 13 circumbinary planets have been discovered in 11 systems by transit missions. Despite the radial velocity method being the most established technique for planet detection, no circumbinary planets have been detected by radial velocity measurements to date. 

I will present the current status of the BEBOP (Binaries Escorted By Orbiting Planets) RV project, after two years of survey using the HARPS instrument at ESO. Although our sample is limited, we have identified 16 candidate signals consistent with circumbinary companions at this stage. I will outline our methods and review the various candidates that we have. Including one of our most interesting candidates, a second outer circumbinary planet in EBLM J0608-59 (TOI-1338), where TESS recently identified a 95-day circumbinary planet. If this candidate is confirmed, it would make EBLM J0608-59 the second multiplanetary circumbinary system ever discovered.
