[1] The bill to alter the monarch's style and titles was passed by the Parliament of Ceylon on 26 March 1953, and received royal assent on 7 April 1953.

The Act gave Parliament's assent to the adoption of separate style and titles by the monarch in relation to Ceylon.

The royal style and titles proposed in the bill were: Elizabeth the Second, Queen of Ceylon and of Her other Realms and Territories, Head of the Commonwealth.

From my place in our Parliament not long ago, before me a Mace of crystal and precious metal, the gift of that Parliament whose traditions we endeavour to follow, I, of free choice and as representative of my people, cast my vote for a Bill by authority of which Your Majesty has graciously assumed the Title of Queen of Ceylon.

[7] The Royal Titles Act was repealed by the Sri Lankan Constitution of 1972, which abolished the Ceylonese monarchy on 22 May 1972.
