While Donald Trump's unprecedented second state visit to the UK will have all the elements of a traditional trip - pomp and pageantry, a state banquet and a bilateral with the PM - it will look markedly different to ones for other heads of state. There will be no carriage ride through the town, no trip to London to see the grave of the Unknown Warrior at Westminster Abbey and no address to Parliament.
These tweaks mean there will be no public-facing elements amid security concerns and potential hostility from demonstrators. Mass protests are expected to be staged by the Stop Trump Coalition in both Windsor and London, with security being tightened during his stay. Thames Valley Police has launched what it has described as a "significant" and "very comprehensive" policing and security operation for the state visit, with officers from forces across the country drafted in.
Two special additions have been added to the state visit itinerary, a visit to St George's Chapel and a special Beating Retreat military spectacle - which marks the first time one has been carried out for an incoming state visit.
The trip, which was originally planned over three days, was shortened due to Mr Trump's busy diary.
It is historic as US presidents serving their second term usually are not offered state visits.

WednesdayWednesday will see the couple greeted by an impressive display of pomp and ceremony.
The Prince and Princess of Wales will play a key part in the high-profile visit, designed to indulge Mr Trump's well-known love of the British royal family.
William and Kate have been tasked with the initial royal meeting of Mr and Mrs Trump on the morning of September 17 in the grounds of the Windsor estate, when they will accompany them to meet the King and Queen for an open-air greeting.
The party will then take part in a carriage procession through the estate to the castle, accompanied by the Household Cavalry, Mounted Regiment, as well as other members of the Armed Forces and three military bands.
Unlike Mr Macron's state visit in July, the carriage ride will not travel through the town.
A ceremonial welcome with a guard of honour will be staged in the quadrangle of the castle as is the custom, followed by lunch with the royal family, and a visit to see a Royal Collection exhibition within the castle.
The president and his wife will visit St George's Chapel privately on Wednesday afternoon to lay a wreath on the tomb of Queen Elizabeth II, and then be given a short tour of the chapel and hear a musical performance from choristers of St George's Chapel Choir.
The Beating Retreat will see the Trumps, King and Queen and Sir Keir Starmer and Lady Starmer join US and British military families to watch the colourful pageant of military music and precision drill.
They will also be treated to a flypast from the Red Arrows and UK and US F-35B fighter jets.
The highlight of the visit will be the glittering banquet on Wednesday evening for 160 guests in the grand St George's Hall.
Both Charles and Mr Trump will deliver speeches before food is served.
The final day of the trip will see the US President welcomed to Chequers by the Prime Minister, while Mrs Trump conducts engagements in Windsor.
The Queen will show the First Lady Queen Mary's Dolls' House and the Royal Library at Windsor Castle; before joining the Princess of Wales at Frogmore Gardens to meet the Chief Scout.
While at the PM's official country home, Mr Trump will spend time with both Sir Keir and his wife, Lady Starmer.
The two leaders will view the Sir Winston Churchill archives before holding a bilateral meeting and a press conference.
During Trump's last state visit at Buckingham Palace in 2019, Mr Trump visited the Abbey and also went for tea at Clarence House.
There will be no visit to Parliament as the House of Commons will be in recess for the party conference session.
Police operationPolice officers from across the length of the country will be involved in the large-scale policing and security operation in both Windsor and Chequers.
Around two-thirds of officers on the ground will be from other forces, with Thames Valley Police providing the rest.
The exact number of officers has not been confirmed.
Responding to a question from the Express, Thames Valley Police's Assistant Chief Constable Christian Bunt, who is responsible for the overall policing and security mission as Gold Commander, said police have "no specific intelligence" regarding protests.
He said: "We will always plan and anticipate that we could well get protests as part of these operations.
"We have specialist resources that are in position to deal with that, as well as the officers on the ground that will do that. We have a duty and a long legacy in Thames Valley Police of facilitating peaceful protest and we will have the resources in place to be able to do that should we get any."
He added they are working "particularly closely" with the Metropolitan Police's close protection unit, as well as colleagues from Buckingham Palace, the Royal Household, Government, local authorities, military and other emergency services.
Assistant Chief Constable Bunt told reporters on Monday the police have "taken into consideration just about every eventuality".
A major drone operation has been launched as part of the security measures, including no-fly zones over Windsor and Chequers.
Specialist Search Unit officers were photographed scouring bollards, bins and drains outside the royal residence in Berkshire where there is a 24-hour-a-day policing operation.
Fencing has also been erected around part of the Long Walk by Windsor Castle.
The operation has taken some three months to plan, with armed officers also patrolling the town.
