"Queen's speech likely to be delayed"
A government source said the Queen’s speech took a week to be prepared, hinting it was likely it would be delayed by a few days. For the speech to be given as scheduled, the contents would need to be decided by Tuesday morning.
Also known as the gracious speech, it was historically written on vellum with ink that takes three days to dry. Although it is now written on thick goatskin parchment paper, this also needs several days to dry, meaning a speech cannot be amended at the last minute.
