The Queen welcomed the President of Indonesia to Buckingham Palace yesterday for the first state visit of her busy Diamond Jubilee year.
The Duke of Edinburgh joined the Queen to greet Dr Susilo Bambang Yudhoyono, 59, and first lady Ani Bambang Yudhoyono at Horse Guards Parade for the start of their three-day trip to the UK.
While the royals waited for their guests to arrive, Philip was seen tugging at the Lord Mayor of Westminster’s ceremonial robe.
He appeared to be admiring Angela Harvey’s royal blue and gold embroidered gown while the Queen waited with Prime Minister David Cameron.
The Duke wore a formal gown himself on Tuesday when he was awarded an honorary doctorate of marine science by Plymouth University.
Home Secretary Theresa May and Foreign Secretary William Hague also greeted Dr and Mrs Yudhoyono before they joined the Queen and Duke for a state carriage procession along the Mall to the Palace, where they will stay during their visit.
The Queen and Philip visited Indonesia 33 years ago.
During his stay, the president will meet International Development Secretary Justine Greening, before rounding off his visit with a speech at the Indonesia-UK Business Forum on Friday.
