The Olympic flag lands in Rio de Janeiro, marking the official start of preparations for 2016. Hot off the heels of London's closing ceremony, the flag arrived in the Brazilian city which will host the Olympics in four years time. Rio has been criticised for construction delays and cost overruns. But the authorities have insisted they can deliver. In London, Brazil's Olympic team prepared for the journey home. Many are hoping Rio can emulate London's success by getting local crowds behind the home team. Brazil's female volleyball squad have already been welcomed home after winning gold. Crowds gathered as the team held a victory parade through the streets of Sao Paulo. Brazil won a record number of medals in London and are hoping to improve the tally in 2016. Head coach Ricardo D'Angelo was hopeful Rio could emulate London's success. SOUNDBITE: HEAD COACH OF BRAZILIAN OLYMPIC ATHLETICS TEAM, RICARDO D'ANGELO, SAYING (Portuguese): "The impressive thing here in London was the crowds. The crowds were fantastic. They cheered Team GB with all their heart, and they were very polite. We hope that in Rio all Brazilians will also participate in the Olympics Games as the British did."
