Abstract	Lepton flavour violation (LFV), and lepton flavour university violation (LFUV), are a striking signature of potential beyond the Standard Model physics. This talk presents recent searches for LFV and LFUV with the ATLAS and CMS detectors, using proton-proton collisions with a centre of mass energy of 13 TeV. A broad range of models and signatures are considered, including leptoquarks, heavy neutral leptons and EFT interpretations, charged-LFV in top quark decays, measurements for W branching ratios to different flavours, and a new measurement of R(K).
