In a resignation statement posted on Facebook, Dabro, who was also minister for agriculture, forestry and fisheries, said that he did not want to be a distraction to the government.

He said he had been subjected to “significant pressure and threats” over plans to reform the department.

The footage was made public earlier in the week.

Dabro’s party is in a coalition government with Prime Minister Andrej Plenkovic’s centre-right Croatian Democratic Union (HDZ) party.

Last November, Health Minister Vili Bros was sacked ahead of a corruption investigation.

On Monday, Zoran Milanovic was re-elected president for a second term, winning almost three-quarters of votes cast ahead of opponent Dragan Primorac, who was backed by the HDZ party.

After the result, Plenkovic said that “Milanovic offers nothing” and declined to congratulate him. Presidents in Croatia fulfil a largely ceremonial role.
