A goal of the LHCb experiment is to measure the CKM angle with a precision of 1$^\circ$. At this precision it is hoped that hints or indeed an observation of physics beyond the standard model could arise. In order to reach this precision it will be necessary to target a number of decays modes. Results from two analyses are presented here which make use of the entire Run1 and Run2 dataset collected at the LHCb experiment. One of them leads to a measurement of $\gamma=(68.7^{+5.2}_{-5.2})^\circ$, which is the most precise result from a single measurement.
