Britain's participation in the Libyan conflict settlement may cost the country 1.75 billion euros ($2.36bn), or seven times more than estimates say, the Guardian reported citing research by military analysts.
"Although Muammar Gaddafi's regime has crumbled in recent weeks, RAF airstrikes against forces remaining loyal to him have continued at an exceptionally high rate, depleting stockpiles of expensive precision weapons the Ministry of Defense will want to replace," RIA Novosti quoted the newspaper as writing.
"That will add to the overall bill, which is still rising and which the Treasury has promised to meet from its special reserves," it said.
Massive demonstrations against longtime leader Gaddafi broke out in Libya in mid-February. The international NATO-led military operation began on March 19 following a UN resolution on "targeted measures" to protect civilians.
Gaddafi's opponents now control much of Libya's territory.
