State expenses on govt vehicles, meetings, tours, etc in budget

Every year we come to know the budget allocation and expenditure on various sectors no matter which government is in power. But unfortunately, we never come to know the public expenditure on some major and important matters like (1) Purchase of new cars for the ministers and government officials (2) Expenditure on P.O.L, repair and maintenance of government vehicles (3) Expenditure on foreign tours of ministers and government officials (4) Expenditure for payment of honorarium to government officers and (5) Expenditure on state functions, meetings, and conferences which are increasing alarmingly every year.
We would like to request our finance ministry to kindly include the above expenditures in the future national budget for the sake of our right to information, accountability and transparency.
