The opulent banquet at Windsor Castle, serving as the highlight of President Donald Trump’s state visit to the UK, was marred by a heated dispute behind the scenes, The Daily Mail reports.

During the grand dinner, Trump and his wife Melania were hosted by King Charles, Prince William, and Princess Kate, surrounded by numerous prominent business leaders and diplomats from both the UK and the US.

While the 160 VIP attendees relished their three-course meal amidst the elegant setting of Windsor Castle’s St George’s Hall, tensions simmered out of sight.

Sources have told the Daily Mail that several members of the Secret Service team guarding the President went into the kitchen to oversee the preparation, and even tasting the food – which some kitchen staff felt was disruptive.

The guests were blissfully unaware but the atmosphere in the kitchen quickly became tense as tempers began to fray between kitchen staff and visiting American security.

The royal source said: ‘The banquet was a resounding success in the main hall, but there was a disruption behind the scenes.

‘Tensions flared between the chefs preparing the meal and the US security team responsible for protecting the President and his entourage.

‘The chefs, working to plate three courses flawlessly, grew frustrated as US Secret Service agents repeatedly checking and even sampling all the food.

‘What began as quiet irritation escalated into a heated exchange, with raised voices on both sides.

‘It took several minutes for tempers to cool and for the kitchen to return to its usual rhythm.

‘Guests in the hall remained completely unaware of the row, but in the kitchen, it was impossible to miss.’

The opulent three-course dinner menu – which was written in French – consisted of Hampshire watercress panna cotta with Parmesan shortbread and quail egg salad to start, brought to a table set with 1,452 pieces of silver cutlery and five wine glasses a head.

This was followed by organic Norfolk chicken ballotine wrapped in courgettes with thyme and savoury infused jus with vanilla ice cream bombe and Kentish raspberry interior sorbet interior, decorated with poached plums to finish.

There was also an abundant wine list including a 2016 English vintage sparkling wine from the Wiston Estate for aperitif and then Domaine Bonneau de Martray, a dry white wine for the starter.

The main course was accompanied by a white Corton-Charlemagne, Grand Cru 2018, and a red Ridge Vineyards, Montebello, 2000 with the champagne being Pol Roger, Extra Cuvee de Reserve 1998.

After dinner drinks were also chosen with care – including a 1945 vintage port in honour of Trump being the 45th US president and a 1912 cognac – the year his Scottish mother was born.

Although Trump is a well-known teetotaler, guests were also able to enjoy a special cocktail created for the banquet, the Transatlantic whisky sour which mixed Johnnie Walker with marmalade, pecan foam and a toasted marshmallow on a biscuit.

Trump is said to avoid alcohol following the death of his brother Feddie at 42 from drink and he once said: ‘It was a very tough period of time. If you don’t start, you’re never going to have a problem. If you do start you might have a problem. And it’s a tough problem to stop.’

The ‘head’ of the 47m table sits in the middle for a Windsor State banquet and King Charles was next to guest of honour Trump, who also sat alongside the Princess of Wales and who he complemented several times.

They faced first lady Melania, who was in between Queen Camilla and the Prince of Wales and TV footage of the event appeared to show the royals and the Trumps getting along famously – all without knowing what was going on backstairs.
