MPs are to pay tribute to Baroness Thatcher in a special session of Parliament following her death at the age of 87.
David Cameron announced that the Commons was being recalled on Wednesday, as he hailed the lasting legacy of a "great Briton" who defied barriers.
In a statement outside Downing Street on Monday, Mr Cameron said: "Margaret Thatcher didn't just lead our country - she saved our country...
"Margaret Thatcher took a country that was on its knees and made Britain stand tall again."
He added: "We can't deny that Lady Thatcher divided opinion.
"For many of us, she was and is an inspiration.
"For others she was a force to be defined against.
"But if there is one thing that cuts through all of this - one thing that runs through everything she did - it was her lion-hearted love for this country.
"She was the patriot prime minister and she fought for Britain's interests every single step of the way."
