The European Union is a single market of 27 countries. While the bloc was officially formed in 1993, it took its member states 25 years longer to agree on the creation of a common public prosecutor’s office.

The office is responsible for prosecuting and bringing charges against those accused of crimes against the financial interests of the EU. But Poland, Hungary, Ireland, Denmark and Sweden remain outside of the agreement.

So, without the support of all the member states, how much authority does it have to do its job? The European chief prosecutor, Laura Kovesi, talks to Al Jazeera.
