Page "Loyal opposition" Paragraph 3

The concept of a " loyal " parliamentary opposition came to be rooted in the other countries due to their being former British colonies, to which British parliamentary institutions were transported.

Thus, the phrase His Majesty's Loyal Opposition existed in some Commonwealth realms even before the title of prime minister.

Also, in federal countries, such as Canada and Australia, the phrase Her Majesty's Loyal Opposition is also employed in provincial or state legislatures, in the same fashion as in other parliaments.
