Abstract: Let $ T$ be a positive closed current of bidimension (1,1) and unit mass on the complex projective space $ {\mathbb{P}}^n$. We prove that the set $ V_\alpha(T)$ of points where $ T$ has Lelong number larger than $ \alpha$ is contained in a complex line if $ \alpha\geq2/3$, and $ \vert V_\alpha(T)\setminus L\vert\leq1$ for some complex line $ L$ if $ \alpha\geq1/2$. We also prove that in dimension 2 and if $ \alpha\geq2/5$, then $ \vert V_\alpha(T)\setminus C\vert\leq1$ for some conic $ C$.
