AB  - Semileptonic 𝐵-meson decays involving the quark transition 𝑏 → 𝑐𝑙𝜈 provide excellent sensi-tivity to probe potential lepton-flavour universality violation. This work introduces two recentmeasurements related to tests of light-lepton flavour universality using a data sample collected atthe Υ(4𝑆) resonance on the Belle II experiment corresponding to an integrated luminosity of 189fb−1. Measurement of the ratio of the branching fractions of inclusive 𝐵 → 𝑋𝑒𝜈𝑒 and 𝐵 → 𝑋 𝜇𝜈𝜇decays and measurement of angular asymmetries of 𝐵0 → 𝐷∗− 𝑙𝜈 decays agree well with standardmodel expectation.
