### Description

Measurements of CP asymmetries in charmless two-body B-meson decays can be a powerful way to provide stringent tests of the Standard Model. In particular a longstanding anomaly in the CP asymmetries of B decays to a kaon and a pion, known as the K$\pi$ puzzle, can be a hint of physics beyond the Standard Model. We present new results from the analyses of charmless 2-body B decays with kaons and pions in the final state at LHCb.
