Where does Britain's tea come from?

While we drink millions of cups of tea each day, how many of us know where our tea actually comes from?
Adventurer and journalist Simon Reeve heads to east Africa to uncover the stories behind Britain's favourite drink.
Most of the leaves that go into our teabags do not come from India or China, but are bought from an auction in the coastal city of Mombasa in Kenya.
From here, Simon follows the tea trail through the epic landscapes of Kenya and Uganda and meets some of the thousands of people who pick, pack and transport it.
In this clip he visits a tea plantation and has a go at picking tea leaves himself.
