The winner of a contest to find the best bottom in Brazil has been crowned despite allegations two candidates bribed judges to rig the votes. 
In its third year, Miss BumBum has a huge following in the country and around the world and titleholders often go on to become national celebrities. 
This year's winner was Dai Macedo, 25, from the central state of Goias, who impressed judges with her 42in derrière.

Eliana Amaral, from Pernambuco in north Brazil, was awarded second place while bringing up the rear was Jessica Amaral from the central northern region of Para who came third.

Ms Macedo, an administration student, had been embroiled in controversy leading up the event when she suggested on social media that the result would be fixed to give the title to rival Mari Sousa.

The contest was plunged into further chaos when rivals accused Ms Sousa, 25, and Ms Amaral, 24, of paying thousands of pounds to the event's judging panel for the right to come first and second. 

Brazil's O Dia newspaper reported that Ms Amaral, a law student representing the northeastern state of Pernambuco, had allegedly paid organisers around £18,000 for second place

The O Dia newspaper also alleged that Ms Amaral's impressive derriere is not entirely natural - which would eliminate her from the competition - and that an X-ray she says proves she has no implants in her bottom is fake.

Contestants took to Twitter to insult each other in the lead up to the competition.

Speaking after her win, Ms Macedo said: 'I'm all emotional. I didn't expect to win.

'All hell broke loose on social media sites but now I can say the contest was real.'
