A rough translation of the poster reads:
"Xavier Bettel has been missing from the Chamber of Deputies since the budget discussions. There is no current information on his whereabouts. Please send any relevant information to ahoi@piraten.lu. We hope the honourable Mr Bettel makes an appearance in time for the Christmas festivities."
The poster then goes on to give a description of the Prime Minister, saying he is often seen wearing a suit and enjoys eating croissants.
Opinions on the poster appear divided, with some users on Facebook calling it unprofessional, while others appreciate the humour.
