Mitt Romney has told his wife that she gave a "fabulous" speech to the Republican National Convention.

To the cheers of convention delegates, Romney joined his wife Ann on stage at the end of her speech at the party's convention at the end of her speech.

In a speech aimed at showing the warm, human side of her husband, Ann Romney told of how they have stood together through tough times in their 43 years of marriage, including her battles with multiple sclerosis and breast cancer.

She told delegates that her husband had worked hard to achieve his success, and she said it "amazes" her to see that success being "attacked."

Ann Romney also set out to show that she and her husband understand the plight of America's struggling families. She spoke of Americans who need to work extra hours to make ends meet, and who don't know how they will pay the rent or the mortgage. And she said it's women who often bear the heaviest burden.

She said her husband is someone who "will not fail" and "will not let us down."
