Cerar will meet his Estonian counterpart Taavi Roivas for talks on bilateral relations, especially the opportunities for reinforcing economic cooperation, the prime minister's office said.

The prime ministers are also expected to discuss e-government as Estonia is one of the leading countries in implementing digital government.

In addition, Cerar and Roivas are expected to cover topical issues such as the Ukraine crisis and the recent Greek election.

Cerar will also meet President Toomas Hendrik Ilves to discuss international issues such as relations between Russia and Ukraine and the Western Balkans.

On Wednesday, Cerar will attend a meeting of senior officials of ALDE group members to discuss common ground on priority EU matters for the liberals.

In particular, ALDE members are expected to demand unfettered free movement of persons within the EU in spite calls for tighter controls due to terrorism threats.
