Indian tea workers 'spraying without protection'

Several of the world's biggest tea brands including PG Tips, Lipton, Tetley and Twinings have said they will work to improve the tea estates they buy from in India after a BBC investigation found dangerous, disgusting and degrading living and working conditions.

Harrods has stopped selling some tea products in response.

The joint investigation by Radio 4's File on Four and BBC News also found a shocking disregard for health and safety on some tea plantations in Assam.

The BBC's South Asia correspondent Justin Rowlatt reports.
