The UK could have a new permanent Bank Holiday to mark Queen Elizabeth's 70 years of public service.
The plans are being considered by chancellor Rishi Sunak, and would be a day of commemoration of the Queen's 'extraordinary service' over her reign spanning seven decades.
It comes as campaigners have called for this year's additional Bank Holiday on June 3, which will mark the Queen's Platinum Jubilee, to be made permanent.
Rishi Sunak is reported to be examining the costs and benefits of the proposal, the Mirror reports.
If put in place, it would increase the number of Bank Holidays in the UK from eight to nine days a year.
This would still leave the UK behind Austria, France, Norway, Italy, and Denmark.
Estimates made in 2010 differed considerably in their cost projections for a bank holiday, with unions estimating £1bn, government £2.9bn and the CBI £6bn.
Nonetheless, the plan is supported by the Confederation of British Industry (CBI), Hospitality UK, the Archbishop of Canterbury, and others.
A report also said Downing Street asked the Department for Digital, Culture, Media & Sport (DCMS) to review the matter.
It cited a source as saying: "The Treasury is not saying no off the bat despite previously being institutionally allergic to the idea of a new bank holiday.
"Rishi is supportive of the campaign and the thought behind it and has asked for all the projected costs."
Queen Elizabeth II is the longest reigning British monarch, and the first in history to celebrate their Platinum Jubilee, which marks 70 years on the throne.
The previous longest reigning monarch was Queen Victoria, who reigned for 63 years and 216.
Elizabeth surpassed her on September 9 2015 and if she is still reigning on May 27 2024 she will pass Louis XIV, who ruled France from 1643 to 1715, to become the longest reigning monarch of any sovereign state.
