Pubs could stay open later to mark the marriage of Prince Harry and Meghan Markle.
The wedding is planned for 18 May at St George’s Chapel at Windsor Castle.
The Home Office has launched a four-week consultation on plans to let bars and other licensed premises open on the nights of Friday 18 and Saturday 19 May until 1am the following morning.
Home Secretary Amber Rudd said: “The Royal Wedding will be a time of national celebration, and we want everyone to be able to make the most of such an historic occasion.
“I hope that this relaxation of the licensing hours will allow people to extend their festivities and come together to mark what will be a very special moment for the country.”
Brigid Simmonds, chief executive of the British Beer and Pub Association, said the extended hours could boost the pub trade by £10m.
She added: “Visitors see the Great British pub as a cultural icon, almost as much as the Royal Family.”
The Royal Wedding will also coincide with the FA Cup Final.
Licensing hours were previously extended for Prince William’s marriage to Kate Middleton in 2011 and for the Queen’s 90th birthday in 2016.
