"I have arrived at the conclusion that there are not sufficient guarantees to carry forward a common agenda to reform Europe," the former Belgian premier said, adding that "there is not enough common ground to proceed with the 5-Star Movement's request to join the ALDE group". He said "there remain fundamental differences on key European questions". ALDE was to have voted on admitting the M5S on Tuesday. That vote has now been scrubbed. (ANSA)
