The present invention relates to a catalytic process for the preparation ethylene glycol from a saccharide containing feedstock. More specifically, the invention relates to a process for the selective conversion of saccharide to ethylene glycol using a catalyst system under acidic conditions, the process comprising conversion of a feedstock comprising at least one saccharide and comprising the steps of: i) contacting the feedstock comprising at least one saccharide with a catalyst system in the presence of hydrogen and a reaction medium; and ii) obtaining ethylene glycol from the reaction mixture; wherein the catalyst system comprises: a) tungsten, molybdenum, or a combination thereof; and b) one or more transition metals selected from IUPAC Groups 8, 9 and 10, and combinations thereof; and wherein step i) is conducted at a pH of from 2.0 to 6.5.
