If there is an international award for the sheer magnificence of its glittering white tie events, on the evidence of tonight's spread Sweden would bag first prize.

The Nobel Prize Banquet held at Stockholm's City Hall was a blaze of gold candelabra, rows of hand-tied floral arrangements, and richly attired royals hosting the world's biggest brains and brightest talent after the Nobel Prize ceremony at the city's concert hall tonight.

And the women of Sweden's royal family pulled out all the stops - along with the family jewels - to look their best for the splendid occasion with Crown Princess Victoria, 38, Princess Madeleine, 33, and their sister-in-law Princess Sofia, 30, dusting off the Bernadottes' most eye-catching tiaras to wear with their floor-length evening gowns.

After presenting the awards, King Carl XVI Gustaf, his family and their partners were seated at the 'honour table' for the traditional Nobel banquet.

When the winners of the Nobel Prizes in literature and sciences received their prizes from King Carl at the Stockholm Concert Hall, they did so against a backdrop of flowers.

Earlier today, the winner for the prestigious prize was revealed as the National Dialogue Quartet, which won the Peace Prize for helping build democracy in the birthplace of the Arab Spring.

They accepted the prize at a ceremony in Oslo held under tight security following the armed attacks in Paris.

At the earlier ceremony in Oslo, Norway's King Harald V and his wife Queen Sonja attended the annual award ceremony along with Prince Haakon and his wife Crown Princess Mette-Marit.

Each year the scientific and literature awards are presented in Stockholm, Sweden, while the Nobel Peace Prize is handed out in Oslo, Norway.

'Today we are most in need of making the fight against terrorism an absolute priority, which means perseverance on coordination and cooperation between all nations to drain its resources,' Hussein Abassi, head of the Tunisian General Labour Union, one of the quartet honoured, said in a speech.

The Nobel Prize giving ceremony took place at the Concert Hall in Stockholm, Sweden. Events then progressed to the banquet at City Hall

The Tunisian National Dialogue Quartet was awarded the 2015 Nobel Peace Prize for its decisive contribution to the building of a pluralistic democracy in Tunisia in the wake of the Jasmine Revolution in 2011

Hussein Abassi spoke out about the plight of Palestinians and the need to keep fighting terrorism

As well as maintaining the war on terrorism, the pro-democracy group called for Palestinians to be given the right to self-determination.

'We need to accelerate the elimination of hot spots all over the world, particularly the resolution of the Palestinian issue and enable the Palestinian people the right to self-determination on their land and build their independent state,' he said.

Security was tight at the event in Oslo with personnel positioned over the banquets and concerts for hundreds of political, intellectual and business leaders attending the lavish Nobel awards ceremonies held jointly in Oslo and Stockholm.

'Security is higher than it would otherwise have been because of the situation in Europe,' Johan Fredriksen, chief of staff for Oslo police told Reuters, referring to the Paris attacks in which 130 people were killed.

Last year, a demonstrator carrying a Mexican flag disrupted the ceremony at Oslo City Hall when Pakistani teenager Malala Yousafzai and Indian activist Kailash Satyarthi received their Nobel Peace Prizes. He was not a guest but managed to get through the security checkpoints.

The quartet of the Tunisian General Labour Union, the Tunisian Confederation of Industry, Trade and Handicrafts, the Tunisian Human Rights League and the Tunisian Order of Lawyers was formed in the summer of 2013.

As well as maintaining the war on terrorism, the pro-democracy group called for Palestinians to be given the right to self-determination

The pro-democracy group accepted their award and made a passionate speech for Palestinian rights and a call for the continued fight against terrorism

It won the award for the role it played in the peaceful transition of power in Tunisia in a region struggling with violence and upheaval.

With a new constitution, free elections and a compromise arrangement between Islamist and secular leaders, Tunisia has been held up as a model of how to make the transition to a democracy from dictatorship, said Kaci Kullman Five, head of the Norwegian Nobel Committee.

Last year Tunisia held successful legislative and presidential elections but the country has been hit by violence this year. In March, Islamist gunmen killed 21 tourists in an attack at the Bardo Museum in Tunis, and 38 foreigners were killed in an assault on a Sousse beach hotel in June.

'In this time of terror, the threats against Tunisia and the Tunisian people are indistinguishable from the threats against other countries,' she said in her speech.

'I came here to share this extraordinary moment with the whole of Tunisia. I am so proud,' said Haddad Fayssal, a 39-year-old Tunisian engineer from Paris, draped with the red-and-white flag of the North African nation over his shoulders.

'This prize is a powerful message against all types of extremism and terrorism. It is a message that we can all live together,' he told Reuters outside Oslo City Hall, the peace award ceremony's venue.

In neighbouring Sweden, the Nobel Prize winners in literature, chemistry, physics, medicine and economics gathered in Stockholm to receive their prizes from the King of Sweden later in the day.

Belarussian author Svetlana Alexievich won the literature prize for her portrayal of the harshness of life in the Soviet Union.

In Stockholm, the winners will collect their medals at a concert hall before attending a banquet at the city hall, which will include VIPs like European Central Bank President Mario Draghi.
