The Princess of Wales joined King Charles and Queen Camilla for a formal welcome to Oman's Sultan Haitham bin Tarik, braving the pouring rain. Catherine greeted the visiting ruler with a warm smile and a deep curtsy before shaking his hand.

The King, meanwhile, removed his top hat to welcome the Sultan, exchanging a broad smile with his guest as they met. Despite the persistent rain, the royals and their guests made their way into the ornate horse-drawn coaches without reaching for umbrellas.

Queen Camilla brought a vivid splash of colour to the occasion in a red wool-crepe dress and coat by Fiona Clare, topped with a Philip Treacy hat. Rather than accompanying Prince William to greet the Sultan, Catherine waited alongside the King and Queen for the formal reception.

The event, held at the heart of London, showcased the enduring diplomatic ties between the United Kingdom and the Sultanate of Oman. Observers noted the seamless coordination between the royal household staff and the security details despite the inclement weather conditions.

The Sultan of Oman, known for his focus on regional stability, arrived in the UK for a series of high-level meetings aimed at strengthening bilateral trade and defense cooperation. The royal welcome serves as a symbolic gesture of the deep-rooted friendship between the two nations.

As the procession moved toward the palace, the sight of the royal carriages navigating the wet streets provided a classic image of British pageantry. The lack of umbrellas among the primary royals was seen by many as a sign of resilience and adherence to traditional protocol.

Princess Catherine's choice of attire and her composed demeanor were widely praised by fashion critics and royal correspondents alike. Her presence alongside the King and Queen underscored her growing role as a central figure within the monarchy.

The formal reception inside the palace followed the outdoor ceremony, where discussions were expected to cover a range of geopolitical issues. Both the British and Omani delegations expressed optimism regarding the outcomes of these diplomatic engagements.

Security personnel remained vigilant throughout the proceedings, ensuring the safety of the visiting dignitary and the royal family members. The event concluded without any disruptions, marking a successful start to the Sultan's official visit.

As the day progressed, the focus shifted from the ceremonial welcome to the substantive talks scheduled for the remainder of the week. The visit is expected to yield significant agreements in the sectors of energy and education, further cementing the partnership between London and Muscat.
