Party breakdown of cabinet ministers: Source:[4] The cabinet is a two-party minority government composed of the Croatian Democratic Union (HDZ) and the Independent Democratic Serb Party (SDSS).

Together these parties have a delegation made up of 64 Members of Parliament (out of 151 in total) and are thus short of an overall majority of 76 MPs by 12 seats.

The government thus relies on outside parliamentary support from other parties and individual MPs to achieve such a majority.

This support is provided by the HDZ's pre-electoral coalition partners - HSLS, HDS, HDSSB and independent MP Marijana Petir, as well as by MPs from several smaller parties - HNS-LD, NS-R, the Democratic Union of Hungarians, Kali Sara and the Union of Albanians, and finally by two independents representing national minorities - Furio Radin and Vladimir Bilek.
