Summary of CKM 2023 working group 5: Direct CP violation (DCPV) including ${\phi }_3\mathrm{/}\gamma$ from $B\to DK$, DCPV effects, branching fractions and polarisation in charmless $B_{(s)}$ decays

In this contribution a summary of the activities of Working Group 5 (WG5) presented during the 12th International Workshop on the CKM Unitarity Triangle (CKM2023) is reported. This includes new results on ${\phi }_3\mathrm{/}\gamma$ measurements using $B\to DK$ decays, search for $CP$ violation using charmless $B$ decays and $b$-Baryon decays, measurement of branching ratios in hadronic $B$ to charm decays, and theory of three-body nonleptonic $B$ decays.
