A new measurement of the longitudinal spin asymmetry A{sub 1}{sup d} and the spin dependent structure function g{sub 1}{sup d} of the deuteron is presented in the Q2 range from 1GeV2 to 100GeV2 and the x range from 0.004 to 0.7. The data were taken in 2002 and 2003 with the COMPASS experiment at CERN, scattering 160 GeV2 polarised muons off a large polarised 6LiD target. While significantly improving statistical accuracy in the low x region the data agree nicely with previous experiments.
