A consortium of British humanitarian agencies is a group of organisations that work together to help people in need. They might help people in different countries around the world, or they could help people in the UK. They might give clean water and food to people who don't have enough, or they could provide medical help to people who need it. They might even give shelter to people who don't have anywhere to live. All of these organisations come together to make a difference in the world and help people who need it.
