Cameron's will be the first visit by a British prime minister to Slovenia.

It comes as the UK prepares to hold a referendum next year on its EU membership, as part of which it has launched a drive for reforms of the bloc.

The British prime minister has so far visited Berlin, Paris, Warsaw and The Hague as part of the reform tour.

In February, UK Foreign Secretary Philip Hammond visited Slovenia with the same agenda.

The visit should also provide an opportunity to examine opportunities for enhancing what are already good and friendly relationship between the two countries, Cerar's office has said.

Cerar and Cameron will address the press at 8:30 PM.
