Qatar has promised changes to improve the welfare of foreign workers - without those changes, their World Cup tournament may be doomed.
Ten weeks before the start of the World Cup in Brazil, police are making a final push to sweep clean some of Rio's most crime-ridden areas.
Gary Barlow and Gary Lineker unveiled Take That's "Greatest Day" as the official England 2014 FIFA World Cup song as part of Sport Relief.
With 10 weeks to go until the World Cup in Brazil, the military police have been sent in to Rio's favelas - its shanty towns - in a bid to clean up the streets.
ITV News Brazil Correspondent Nick Ravenscroft has joined them on the operation:

The death of another construction worker at the opening World Cup venue in Sao Paolo is expected to put the already heavily delayed building process even further behind schedule, ITV News Brazil Correspondent Nick Ravenscoft has said.
He described the latest death and the resulting delays as both "farcical and tragic".
ANOTHER worker dies preparing #WorldCup stadium. This time number 3 at Sao Paulo where opening match will take place. Now 7 in total. SEVEN.
Surely this means down tools while health and safety assessed. Surely that will put them even further behind schedule. Farcical and tragic.
A seventh construction worker has died while helping to build Brazil's World Cup arenas after falling 25 feet to his death while installing floors on temporary stands in one of the stadiums.
The unnamed worker is the third to lose his life during the construction of the Arena Corinthians on the outskirts of Sao Paolo, the stadium picked to host the tournament's opening match.
Others fatal accidents have occurred in Manaus and Brasilia. Another worker died while working on Palmeiras's arena in Sao Paulo, but that stadium will not be used in the World Cup.
FIFA's secretary general Jerome Valcke said he has "full trust" that Brazil will be ready to host the World Cup in 76 days' time.
Valcke told a press conference in Rio that he believed the developers of the Sao Paulo stadium due to host the opening match on 12 June would deliver on time.
He added that the stadium in the city of Curitiba, which was nearly kicked out of the World Cup last month, is also "on course" for the tournament.
ITV News Brazil Correspondent Nick Ravenscroft has been tweeting from a FIFA press conference at Rio's Maracana Stadium about the country's preparations of the World Cup, which begins in 76 days:
Quote which summarises thrust so far: "we will have 12 host cities and stadiums. But still there is work to do." Jérôme Valcke, FIFA
In other words "keep calm and carry on!" - that's what they're saying in public, at least
Valcke has "full trust" in the developer of Sao Paulo stadium to deliver in time for the opening game. That is June 12th.
Qatar's 2022 World Cup organising committee said it adhered to all of Fifa's rules during its successful bid after a report claimed former Fifa vice-president Jack Warner and members of his family were paid millions by a Qatari company.
– Qatar's 2022 World Cup organising committee
The 2022 bid committee strictly adhered to Fifa's bidding regulations in compliance with their code of ethics.
The supreme committee for delivery and legacy and the individuals involved in the 2022 bid committee are unaware of any allegations surrounding business dealings between private individuals.
Warner, who is currently a politician in Trinidad, denied The Daily Telegraph's report, calling it "foolish" and insisting there is a witch hunt against Qatar.
A Qatari company closely linked to the country's successful 2022 World Cup bid reportedly paid a senior official and members of his family almost $2 million (£1.2m), The Daily Telegraph claims.
Jack Warner, the former vice-president of Fifa, appears to have been paid around £720,000 by the company after Qatar was awarded the prestigious competition, the newspaper reports.
It was also reported that the FBI is now investigating the links between the company, which is controlled by a former Qatari official, and Mr Warner.
Mr Warner strenuously denied the report and said in a statement: "I have no interest in joining in the foolishness that is now passing as news on Qatar and Jack Warner.
"Nor do I intend to join those who are on a witch hunt against the World Cup 2022 venue. And do consider this as my final comment on this matter."
