Only seven weeks before the official Brexit date, Barnier will meet with PM Xavier Bettel and he will later also brief Luxembourg's MPs on the current state of Brexit and possible future outcomes.
Last week, some of Barnier's representatives already came to speak to the chamber commission.
Barnier will not stay long in the Grand Duchy however. He is expected back in Brussels on Monday evening, where he will meet with British Brexit minister Stephen Barclay.
