CHESTER city centre will come to a standstill on Saturday, as the Royal Family visits the town for the society wedding of the year.
The Queen will be among the guests of honour when the Duke and Duchess of Westminster's eldest daughter Lady Tamara marries Edward van Cutsem.
Security will be tight at the city's cathedral and Cheshire police have drawn up an action plan to make sure the arrival and departure of the congregation will be as smooth as possible.
The special Buckingham Palace security team will be on hand to give the Royals added protection.
The Queen is joined on the guest list by Prince Charles, Prince William, Prince Harry, the Duke of Edinburgh and Camilla Parker-Bowles.
The two main routes around the cathedral, St Werburgh Street and Northgate Street, will be closed to all traffic between 10am and 1pm.
Pedestrians will be allowed in the area but they will be kept at a safe distance by a series of barriers.
A Cheshire police spokesman that although security is an issue they wanted the people of Chester to be able to enjoy as normal a day as possible in the city centre.
He said: "We are involved in the security operation but cannot go into details of what that exact role is.
"The decision has been made to close two roads to traffic but that does not apply to pedestrians.
"When we look at policing an event such as this we have to look at the amount of people and how high-profile they are.
"Cheshire police hope the event does not cause a lot of disruption and things carry on as normal as possible."
The Duke and Duchess of Westminster are said to be "truly delighted" for their daughter.
Mr van Cutsem has been a regular visitor to the family's sprawling Eaton Hall estate since he was child and now works as a banker in the city of London.
Both the young princes par-tied the night away at the home which played host to Lady Tamara's 21st birthday party.
