### Description

Overconstraining the unitarity triangle is a key goal of LHCb. The excellent time resolution of the detector lends itself to high precision time dependent CP violation measurements. CP observables in $B^0 ­\to D_{(s)}^{(*)+}D^{(*)‐}$ decays are of great interest as they have the potential to be sensitive to new physics contributions. There is a long­‐existing tension between results from BaBar and Belle on $B^0 ­\to D^+D^‐$. We present results on the CP observables with the full Run 1 dataset.
