"It is high time to move toward closer political integration — the Federal Union of States with broad powers. We know that such an initiative triggers a strong resistance, but someone'd inactivity cannot become a paralysis for everyone. Those who believe in European ideals, should be able to give them a new life instead of helplessly observing its slow sunset," the letter published in the La Stampa newspaper read.
The senior officials stressed in the letter that it was necessary to take action until it was too late, referring to the dramatic changes and challenges that the European Union had recently faced, in particular, Brexit and migration crisis.
They also suggested sharing sovereignty in the issues requiring joint approach, like combating climate change and terrorism, as well as in the energy sphere, finances and migration policy.
In September 2015, Lammert, Bartolone, Boldrini and di Bartolomeo signed a document calling for a faster and deeper European integration to harmonize EU states’ foreign policies and make the alliance more democratic. The document pointed out the major role of national parliaments in improving EU structure and hinted at a possibility of creating the Federal Union of States.
