Prince Harry, the fifth in line to the throne, is set to marry American actress Meghan Markle on Saturday 19 May.
And Islanders could be given the chance to toast the marriage for an additional two hours on both the Friday and Saturday nights after Assistant Economic Development Minister Steve Pallett signed a ministerial decision to extend pub closing times from 11 pm to 1 am on the two days.
However, the plans are still subject to States approval.
Similar plans are also being discussed across England and Wales.
Mr Pallett, who has ministerial responsibility for licensing matters, said: ‘The assistant minister wished to enable the public to celebrate the wedding of Prince Harry and Meghan Markle on 19 May 2018. This decision was anticipated to be in keeping with a decision taken by the UK Home Secretary under the UK Licensing Act 2003 to mark an occasion of national significance.’
The proposed temporary change to the Licensing Law would not affect restaurants and nightclubs, which can already stay open until 1 am or beyond. Off-licences would also remain unaffected by any change.
The couple announced their engagement last November and the wedding is set to take place at St George’s Chapel at Windsor Castle, with the Archbishop of Canterbury, Justin Welby, performing the marriage ceremony.
Pubs were also allowed to stay open for the Royal wedding of Prince William and Kate Middleton in 2011.
