I may be incorrect but I thought we are governed by The Cabinet. And then Parliament.
It's a bit more subtle than that.
The 'government', i.e the body that decides policy and proposes legislation, rules the country but it is answerable to Parliament (which represents 'the people') and Parliament can overrule the government if it has a mind to do so.
As the government has a majority of the votes in parliament it is unlikely to be overruled, unless it tries to push through legislation which is felt by even its own MPs to be damaging, or just completely wrong. In that case they may be defeated because their own MPs vote against them in enough numbers as to destroy their majority.
Never lose sight of the principle that Parliament , the Legislature, is the sovereign body, not the Executive (the government)
The Executive rules on behalf of the monarch. It is the 'monarch in parliament'. Parliamentary sovereignty is meant to check any monarchical tyranny.
We fought a Civil War in the 17th C and executed the monarch to establish this principle. The current government is trying very hard to overturn it.
