An important approach to searching for physics beyond the remarkably successful, but incomplete, Standard Model of Particle Physics is the comparison, with ever improving precision, of the theoretical predictions for weak and rare processes with experimental measurements. This requires good quantitative control of hadronic effects, i.e. the effects of the strong nuclear force. In recent years, lattice computations in Quantum Chromodynamics (QCD), in which space-time is approximated by a discrete lattice of points and results are obtained by large-scale numerical simulations, have reached sub-percent precision for many processes. I will briefly review the consequences of recent studies in precision flavour physics, including some tantalising anomalies, and discuss the prospects for the future.
