London, England (CNN) -- Britain's involvement in the invasion of Iraq "was the right decision and it was for the right reasons," Prime Minister Gordon Brown said Friday in his first response at an inquiry into country's role in the March 2003 conflict.





Brown was answering a question from the chairman of the inquiry, John Chilcot, about whether he thought taking military action in March 2003 was the right decision, especially given that it led to such a great loss of life among military personnel and civilians.





The prime minister said he respects members of the armed forces "who served with great distinction in Iraq" and lost their lives, and to civilians who died.





"I think any loss of life is something that makes us very sad indeed," Brown said.





The inquiry began last year and is expected to be the most thorough investigation yet into decisions that led up to the war and governed Britain's involvement, analysts have said.





It is not a court of law, so the inquiry cannot find anyone criminally responsible or apportion blame. But inquiry members will be able to judge the legality of the conflict.





Brown spent much of Friday defending military spending allowances, which have come under harsh scrutiny in Britain. Earlier witnesses have said Brown, as head of the British Treasury leading up to and after the Iraq invasion, did not allow the Ministry of Defence to spend as much as was needed.





Such cuts would have restricted the military's ability to buy helicopters, body armor and weapons that would have subsequently been used in Afghanistan.





Brown said as chancellor, he never ruled out a military option on the basis of cost.





"I said that every single request that was made for [military] equipment had to be met, and every request was met, and at any point military commanders were able to ask for equipment that they needed, and I know of no occasion when they were turned down for it," Brown testified.

Geoff Hoon, defence secretary at the time of the 2003 invasion, testified that Brown forced cuts that limited military spending.





"We then had to look hard at our budget and make some rather difficult cuts in the future equipment program as a result," Hoon testified.





Brown had faced increasing pressure to testify before Britain holds general elections, widely expected to be held May 6. His Labour Party faces a tight race with the opposition Conservatives.





Chilcot, the inquiry chairman, said committee members previously decided not to call any government ministers who are still serving in posts relevant to Iraq, but Brown offered to testify.





Chilcot announced in January that Brown had agreed to appear in the next two months.





Susan Smith, whose son, Pvt. Phillip Hewett, died in Iraq in 2005, said she doesn't believe Brown did everything possible to equip British troops.





"Was it needed? Was it asked for? If it was, why was it not funded?" she said. "At the moment, you've got no answers. It's all speculation. It would be nice just to know the truth."





Brown has faced repeated criticism for the level of equipment for the 9,000 British troops in Afghanistan, which some have said is too low. The prime minister has defended equipment levels and said he seeks assurances from military officers in the field that troops have the supplies they need.





A military memo, sent in June but released in October, contained a warning from a British officer that a shortage of helicopters was putting troops at risk because they were forced to travel on the ground, increasing the chances a roadside bomb could kill them.





The memo was written by Lt. Col. Rupert Thorneloe, who died a month later in a roadside bombing. At the time, he was the highest-ranking British serviceman to die in combat since the 1982 Falklands War.





Gen. Michael Walker previously testified the Treasury gave defence officials a spending target that they found hard to reach.
