Refugees fleeing Syria's civil war to Britain will be treated with the "greatest urgency", David Cameron said today.
The Prime Minister said the "most needy people" in refugee camps, including v ictims of sexual violence, will be offered a home in Britain.
Labour leader Ed Miliband welcomed a "significant change of heart" from the Government.
No figure is being put on the number of displaced people the UK will take, but hundreds are expected to arrive over the coming year.
Home Secretary Theresa May will announce further details after Prime Minister's Questions.
Mr Cameron told Mr Miliband during Prime Minister's Questions: "What I can assure you of is we will act with the greatest urgency because, when it comes to Syria, we have acted with the greatest urgency throughout.
"We have made available £600 million, which makes us the second largest humanitarian donor, we've provided food for 188,000 people, clean water for almost one million, medical consultations for almost 250,000 and as (Mrs May) will make clear, we will be coming forward with a scheme to help the most needy people in those refugee camps and offer them a home in our country.
"We want to make sure we particularly help those who have been victims of sexual violence, a cause that (Foreign Secretary William Hague) has rightly, on behalf of the whole country, championed across the world."
Mr Miliband had asked the PM: "All sides of the House will welcome the Government's significant change of heart on the issue of Syrian refugees, which I raised with you last week.
"We look forward to (Mrs May's) statement but, now the decision has apparently been taken, will you reassure the House that you will act with the utmost urgency because we're talking about the most vulnerable people in refugee camps who need help now?"
