Here are some of the valid reasons why Joseph Muscat should call it a day and hand over the Labour Party leadership to someone else.
One ‒ the power station obscenity; two - the visit to Baku with “his” team; three ‒ the retention in Castille of Konrad Mizzi and Keith Schembri; four ‒ the very dirty Vitals contract; five ‒ the mysterious American University of Malta. On the whole, however, the biggest reason is that, before 2013, he promised a clean, transparent, corruption-free governance and Malta got the exact opposite.
There might be more reasons but my memory is not what it used to be.
