We summarise the most recent results of the Belle experiment about flavour changing neutral current (FCNC) radiative and (semi-) leptonic B decays. In particular, we report about the first observation of the decays , B→ φ K γ, the inclusive B→ X s ℓ+ℓ–. We also report about searches for B→ ℓ+ℓ– decay and for CP asymmetries in .
