Say Martin Schulz, German SPD leader.
He calls for all member states to sign up to a federal Europe or leave the bloc.

So what does it matter what party leaders set out their aspirations for their future at party conferences?
It is what it is an aspiration of Martin Schulz, nothing more.
More importantly, SPD have agreed a coalition with Angela Merkle.
I can easily add some silly political comments made by politicians of all sorts. It does not mean much because they are what they are.
For instance Ruth Davidson would sack Boris, an aspiration for Ruth Davidson but it does not meant it will happen any time soon.
Boris Johnson wants the EU to go whistle, but it will not happen any time soon.
Phillip Lee, a justice minister, has told a fringe meeting that the welfare state is like a “Ponzi scheme” close to collapse.
There are loads of comments that can be listed, it does not mean that any of them will happen any time soon. They are just thoughts spoken out loud for the benefit of the party faithful.
