This is an announcement for the paper "Spaces of functions with countably many discontinuities" by R Haydon, A Molto and J Orihuela. Abstract: Let $\Gamma$ be a Polish space and let $K$ be a separable and poointwise compact set of real-valued functions on $\Gamma$. It is shown that if each function in $K$ has only countably many discontinuities then $C(K)$ may be equipped with a $T_p$-lower semicontinuous and locally uniformly convex norm, equivalent to the supremum norm.
