Joanna Lumley has described her outrage at how the use of hens in battery cages still dominates the UK egg production market. The actress was speaking out on the eve of the charity Compassion in World Farming’s Good Egg Awards, which she is hosting.62% of the UK's 27 million egg-laying hens are still kept in battery cages, ranking the UK fifth in a European league table.

Tesco would free an estimated 1.3 million birds from cages each year if it moved to selling only barn and free-range eggs.Chief Executive of Compassion in World Farming, Philip Lymbery argued that consumers no longer want to eat food that has been produced in cruel systems.
