Last week the Government put out some updated statistics on living standards in the UK, including the figures on child poverty for 2011-12. This was an extremely thorough, valuable report. The chapter on children is more than 60 pages long, and presents a complex picture of child poverty - the UK is a world leader at producing this sort of research. 

For the last six months two hundred organisations joined forces to call for the end of world hunger.  It has been a busy couple of months with achievements and pauses for reflection along the way. Before we knew it the Nutrition for Growth Summit was on our door step; a key moment for all of us who are concerned by child malnutrition.

As 45,000 people were preparing to gather in Hyde Park for the Big IF rally on Saturday, I was with other IF campaigners at the Nutrition for Growth summit. There with us were Frank, 16, and Mwajuma, 18, two young activists from Tanzania who are in the UK at the moment supporting the IF campaign. Frank told delegates that he, like millions of other children around the world, didn't get the nutritious food he needed as a child. He spoke movingly about a simple vision for the future: "I don't want to see my children suffer like I did." It was the first of many moments throughout the day that sent shivers down my spine.

Stacey Pham from our sports programmes team travelled to The Oval in London last week to see children from local Rights Respecting Schools put their cricket skills to the test with with players from the West Indies cricket team. 

Last week I took 100 children to Downing Street to demand enough food for everyone. The children represented more than 30,000 young people from across the UK who had supported the IF campaign by decorating plates with their messages to Prime Minister David Cameron.

Tomorrow, 8 June , the Big IF rally is taking place at Hyde Park. Join me, my UNICEF colleagues and volunteers from 200 organisations as we make a massive noise for a cause that desperately needs world leaders' attention: undernutrition.
