  Measurements of electroweak boson production provide an important test of the
Standard Model at the LHC energies and allow the partonic content of the proton
to be constrained. $W$ and $Z$ bosons are reconstructed in several leptonic
final states using data samples corresponding to an integrated luminosity of up
to about 1 $fb^{-1}$. Inclusive and associated production cross-sections are
reported.
