Question

how can the parliament control government

Answer 1

discussing matters of urgent public importance, moving call- attention notices and adjournment motions, and also by appointing various committees such as public accounts committee, estimates committee, committee on public undertakings, committee on government assurances, the committee on privileges, the committee on subordinate legislation etc. All these activities keep the executive alert.

Answer 2

I assume you’re talking about a Modern parliamentary democracy such as the UK, Canada or Australia.

The thing is, the executive is intertwined with the legislative in these countries; that is, the legislative decides who is the executive.

The leader of the party that has a majority in the lower house of these countries (and the one house in the case of unicameral New Zealand) is appointed Prime Minister.

If the house is unhappy with their performance as leader of the game government, they can be the subject of a “Motion of no confidence”. This means that the house has lost confidence in the Prime Minister (and their government) and that they are unfit to continue serving as Prime Minister.

This is different for each country, but it might trigger fresh elections, or force the party to elect a new leader and undertake a “motion of confidence” in the government.

Either way they rarely pass, since most times a government is the majority party in the legislative and it wouldn’t be foolish for a party to kick themselves out.

hope you understand this small paragraph.
