Martha's trip to Malawi

A schoolgirl whose lunch blog became an internet hit has travelled to Africa to see how the money she raised is being spent.

Martha started posting pictures of her school dinners online and rating them each day.

The site soon started attracting millions of readers, so Martha asked them to donate money to a charity which helps to feed children in Africa.

She's now travelled to Malawi in the south east of the country to see how the cash she raised is being spent.
