The pounds 30,000 cheque was awarded to Helen Dunmore, who said she would spend the money "very easily" on bills and her mortgage - "people forget that writers do not get salaries". Her book, A Spell Of Winter, is the story of the love between a brother and sister set against the backdrop of the First World War. It is her third novel, and she has also published poetry and children's books. Afterwards, she said: "I would not define myself as a children's writer, poet or novelist because I want to feel we can push the boundaries of what we are."
It was a rare uncontroversial moment for a prize which has generated its fair share of controversy since its launch in January. Last month, two of its five judges lambasted the quality of the 146 books submitted for the award, which is open to women of any nationality.
Val Hennessy, a critic, was reported as saying: "I have judged several prizes before and I have seldom come across so many books that were so bad." Susan Hill, the novelist, called the quality of entries "abysmal, terrible".
Others noted the omission from the shortlist of Pat Barker, who won the Booker Prize last year for The Ghost Road, another book about the typically male subject of war, which had a largely male cast of characters. Because the prize is restricted to women, it has predictably ruffled feathers. Antonia Byatt, like Pat Barker one of the few women to have won the Booker Prize in recent years, admitted she was unlikely to enter.
"I am against anything which ghettoises women. That is my deepest feminist emotion," she told the Independent in January.
A previous launch attempt in 1994, under the sponsorship of Mitsubishi, was derailed after the company took fright at such negative publicity. The late Sir Kingsley Amis said: "If I were a woman I would not want to win this prize. One can hardly take the winner of this seriously."
But Kate Mosse, who chaired the judging panel, defended the Orange Prize against charges of sexism.
She said at the January launch that it was partly inspired by the notorious 1991 Booker Prize shortlist when all six authors were men.
Ironically, two of the shortlisted novels were written from the point of view of men and both books - Julia Blackburn's The Book of Colour and Marianne Wiggins' Eveless Eden - have a colonial flavour more usually associated with the Booker Prize.
Three other writers made last night's shortlist. They were Amy Tan, with The Hundred Secret Senses , Anne Tyler with Ladder of Years, and Pagan Kennedy with Spinsters.
The Orange Prize was set up by female publishers following a casual suggestion by the novelist Salman Rushdie - the former husband of Ms Wiggins.
