Unicef has defended its ambassador David Beckham after private emails purporting to be from the former footballer were published over the weekend.
The emails, which appear to consist of messages between Beckham and his publicist, gave rise to claims in the media that he carried out charity work only in order to earn a knighthood.
The claims have been denied by Beckham, who said in a statement that some of the emails had been doctored and others had been taken out of context.
The former footballer has been an ambassador for Unicef since 2005 and launched 7: The David Beckham Unicef Fund in February 2015.
The charity said in a statement that some of the reports related to alleged private correspondence between Beckham and other parties, which it had not seen and could not comment on.
But Unicef said its ambassadors supported the charity in a voluntary capacity and were not paid for their time and commitment.
The charity said Beckham had generously given his time, energy and support to help raise awareness and funds for its work, and had also given "significant funds personally".
It said: "The 7 Fund supports programmes for children, tackling issues such as malnutrition, violence, Aids and emergencies.
"For example, in June 2016 David visited Swaziland to raise awareness of the devastating drought affecting eastern and southern Africa, helping Unicef reach people around the world with important messages about the need for urgent action."
It said the 7 Fund had raised millions of pounds for Unicef programmes and "reached millions of people around the world with crucial messages about our work for very vulnerable children".
