The man who would be king of Serbia smiles warmly at me as I enter the royal palace in Belgrade.
The crown prince does not have his own political party
There is no hint of a Serbian accent from him as he guides me into the splendid interior.
"The first time I came into the royal palace, it was very emotional for me. This is where my father lived, where my grandfather lived. It was quite something."
His Royal Highness Crown Prince Alexander II of Serbia and Yugoslavia only moved to Serbia in 2001.
Most of his life had been spent in the United Kingdom - and one of his godparents is Queen Elizabeth II.
The Yugoslav royal family was abolished when Tito's communists came to power after World War II.
Alexander was born in Claridge's Hotel in London in 1945. Winston Churchill declared the hotel suite Yugoslav territory for the occasion.

"The previous regime castigated the monarchy, said that we left with trainloads of gold. That would have been great. But it never happened," says the crown prince.
In many ways, he is the last embodiment of the old Yugoslavia, following the final dissolution of the old country this summer when Montenegro and Serbia split up.
The six republics of the former Yugoslavia - Serbia, Montenegro, Croatia, Bosnia, Macedonia and Slovenia - are now six independent states.
New royal role?
Crown Prince Alexander believes there is a role for the monarchy in the new Serbia.

"I do believe a constitutional parliamentary monarchy is a very positive thing. It works very well in Europe and Australia, New Zealand and Canada."
"You have a head of state who is neutral, not a member of any political party. I think a monarch can help provide political stability."
But how much support is there in the country for a return of the monarchy?
"I don't have a coffer to do campaigns, blow up balloons, blow trumpets. But the polls say more than 30% of the people are solid for it - which is more than most political parties here."
'Lack of unity'
He believes Serbia has real potential for the future but that certain actions have to be taken before the country can really move forward.
He believes the former Bosnian Serb leaders, Radovan Karadzic and Ratko Mladic, accused of genocide by the UN War Crimes Tribunal in The Hague, have to be arrested.

"We have to fulfil our international obligations. Even though they will be distasteful for some. But we do have to do it and move ahead towards the European Union and kick start again the negotiations that were suspended. We have to work hard to bring more money, business and investors to Serbia."
"We're suffering from lack of unity and sense of purpose. I don't think there'll be a proper settlement in the region until Serbia is at peace with itself and with its neighbours."
And as for the Serbian language?
"I am improving all the time," he says.
