Gordon Brown has said he will "examine" any questions raised over the bonuses paid to civil servants at the Ministry of Defence.
Referring to the £47 million paid out in bonuses this year alone, the Prime Minister said that some of the recipients had been out to Iraq and Afghanistan.
Speaking as he visited an engine manufacturing plant in Gillingham, Kent, Mr Brown said: "If there are any questions asked over the bonuses, I will examine them.
"I've got to say that some of the people who have received help have been working out in the field and people that have been supporting people out there.
"We want to send a message of support to our armed forces."
Official MoD figures showed a total of £287,809,049 has been paid out in bonuses to civil servants since 2003, the year Britain went to war in Iraq.
The figures have sparked anger among the families of soldiers who have been killed fighting in Iraq and Afghanistan.
