Mr Brown sends his condolences to all those who had died in Burma and China and "all those who are suffering as a result of famine" in Africa. He commends the heroic rescue effort in China, but says progress in Burma was still "slow" but he believed aid from Asian countries would flow into Burma but continued to hold the Burmese government accountable for loss of life in the country.

Mr Brown says pressure from the UN - along with aid from Asian countries - would make a difference but aid agencies believed it was best to concentrate on getting the aid to Burma, rather than "other options that may be available" in the future.
Mr Cameron asks for his best assessment on how direct aid could be delivered if it had to be.
Mr Brown says what has changed in the last few days is the determination of Asian countries to co-ordinate action, backed up by a donors' conference. He says "I don't rule out anything" but aid agencies still believed food drops would be counterproductive, as would military intervention.
Mr Cameron asks whether the £2.7bn tax package would continue next year.
Mr Brown says he wants to continue to help people affected by the abolition of the 10p rate. He says the Conservatives cannot say if they support it or not and accuses them of prioritising inheritance tax and stamp duty.
Mr Cameron says that was "no answer" to the question and says people should conclude it is a "one off" and a "tax con". He says the Institute of Fiscal Studies suggests 18m families would be worst off next year.
Mr Brown says Labour what to help lower and middle income families while the Conservatives want to help "other people". To cheers from Labour MPs he asks why the Conservatives won't say if they support his tax package or not.
Mr Cameron asks why he has not had the courage to go to Crewe and Nantwich, ahead of a by-election on Thursday.
Mr Brown says it is traditional that prime ministers do not go to constituencies before by-elections.
The Conservative leader says Tony Blair, on his way to a by-election, said he had "never understood" that convention and had believed in "leading from the front" - to Conservative MPs' laughter. He suggests Mr Brown has put himself "into his bunker".
