Let $M$ denote the space of signed unbounded Radon measures on $\mathbb{R}$ as is defined by Bourbaki, i.e. $M$ is the dual of $C_c$ where $C_c$ is the space of continuous functions on $\mathbb{R}$ with compact support equipped with the locally convex inductive limit topology. Equip $M$ with the vague topology (i.e. the weak-* topology). Then $M$ is not first-countable and thus not metrizable. However, the subspace of positive measures is Polish.

(i) Is $M$ Suslin or even Lusin?

(ii) Is the Borel $\sigma$-algebra on $M$ the same as the $\sigma$-algebra generated by the evaluations $M \to \mathbb{R}$, $\mu \mapsto \mu B$ for bounded Borel-measurable sets $B \subseteq \mathbb{R}$?
