Abstract
The telescopes of the ORM, La Palma have gained a worldwide reputation in the discovery and characterisation of exoplanets, which demonstrates the powerful synergy that exists between small, mid-size and large facilities such as SuperWASP, the WHT and GTC, in this rapidly evolving field. We outline a WHT programme of near-infrared adaptive optics imaging with NAOMI/INGRID, and near-infrared spectroscopy with LIRIS, of exoplanet host stars to search for associated stellar and brown dwarf companions.
