UK minister Andrew Mitchell begins visit to Burma
The UK's International Development Secretary has called for the release of all Burma's political prisoners on the first day of a visit to the country.
Andrew Mitchell is due to meet top government officials and the leader of Burma's democratic opposition, Aung San Suu Kyi, during his three-day trip.
He told the BBC there were "grounds for cautious optimism" about the prospect of reform.
