Huge numbers of civilians fled from the final battles
A senior Sri Lankan Tamil political leader has urged the government to resettle civilians back to their homes as early as possible.
V Anandasangaree described condition in camps for civilians displaced by the country's war as "horrible".
The head of the Tamil United Liberation Front (TULF) said hundreds of thousands faced misery and hardship.
He said there were food, health and sanitation problems in camps set up for Tamil civilians in northern Sri Lanka.
Many people are having skin diseases as they didn't get a chance to have a shower for days because of water shortage
The United Nations says nearly 300,000 people have been displaced by recent fighting between government forces and Tamil Tiger rebels.
The civilians have been housed in various camps, most of them in Manik Farm, near the northern town of Vavuniya.
The Manik Farm camp site, which is described by the UN as the world's largest displacement camp, houses around 220,000 people displaced by the fighting.
Health fears
Mr V Anandasangaree, the TULF leader, is one of the few remaining long-serving moderate Tamil political leaders in Sri Lanka. He has strongly supported the government's stance against the rebels.
"From the reports I get from the people [in the camps] they are good in some areas and horrible in many," Mr Anandasangaree told the BBC.
V Anandasangaree has been a critic of the Tamil Tigers
"Health, water and sanitation situation is horrible. Many people are having skin diseases as they didn't get a chance to have a shower for days because of water shortage.
"Pregnant mothers and newborn babies go through a harrowing time in the camps due to scorching heat," he said.
The Sri Lankan government accepts that conditions in some of the camps are not ideal but says facilities have been improved in many other camps. It says more land is also being allocated to build new camps to decongest those already full.
The United Nations and other aid agencies have also demanded better access to the camps to carry out humanitarian work.
Sri Lanka's government is wary of aid agencies and has complained that the agencies had helped the Tigers in the past.
Sri Lanka says it plans to resettle most of the refugees within six months.
Mr Anandasangaree, a well-known critic of the Tamil Tiger rebels, the LTTE, also faulted the government for viewing every Tamil civilian in the camps as a possible Tamil Tiger suspect.
Sri Lanka has said it needs time to weed out potential Tamil Tiger infiltrators hiding in the camps.
"The civilians risked their lives while fleeing from the LTTE-held areas as the rebels were shooting at them. If the government suspects such people as Tamil Tigers, then the entire population of the two districts - Kilinochchi and Mullaitivu - should be the suspects," he said.
"Then the government will never solve the problem."

GM has lost its corporate sheen faced with falling sales and a global recessionCar giant General Motors is expected to file for bankruptcy protection later on Monday, marking the biggest failure of an industrial company in US history.
The stricken firm had until 1 June to present a viable revival plan in return for emergency government funding.
Reports say a majority of bondholders have now agreed to a deal giving them at least a 10% stake in what is likely to emerge as a much smaller company.
President Barack Obama is due to give full details at a news conference.
The BBC's Jonathan Beale, in Detroit, says Mr Obama is expected to announce $30bn in new funding for GM.
GM's sales have been hit hard by the financial crisis and the firm has received $20bn (£12bn) in state aid.
In return for more cash the federal government is reported to be receiving a stake of 60% in a new, leaner company due to be re-launched within 90 days.
Senior executives at General Motors have been making final preparations for completely restructuring what was once the world's largest car company, under judicial supervision.
A Chapter 11 bankruptcy filing by GM would rank as the third largest bankruptcy in US history following Lehman Brothers' collapse and the failure of telecoms giant WorldCom.
European deal
The restructuring is likely to drastically change General Motors, with some 20,000 workers thought likely to lose their jobs.
GM has been forced to slash its European operationsOur correspondent says long-established subsidiaries Pontiac, Saturn and Hummer, as well as Saab, the remaining GM brand in Europe, Saab, are under threat as production plants are expected to close across the country.
GM's European arm is likely to be spared bankruptcy following a proposed deal by Canadian car parts maker Magna International to buy GM Europe's Vauxhall and Opel brands.
However, unions fear that jobs may be lost at Vauxhall plants in Luton and Ellesmere Port, which employ 5,500 people.
UK Business Secretary Lord Mandelson said he had received further assurance from GM Europe that Vauxhall production would remain in the UK.
