Morning commuters watched on in amusement as a giant inflatable mug, a sea of floral dresses and passionate Swap Your Cuppa chants passed them by in a conga line that crossed Westminster Bridge, lapped Parliament Square and took over Trafalgar for a Strictly Fairtrade Tea Dance.
Whilst the masses danced and promoted the swap to Fairtrade tea in the shadow of Nelson, a breakaway group along with tea producer Mr. Henricksen from the Chamraj Tea Estate in India, took to No.10 Downing Street for a brief chin-wag with Sarah Brown.
Bystanders were passed pieces of Fairtrade chocolate, The Big Swap stickers and leaflets and chatted with the Fairtrade Tea Ladies about why you should swap to Fairtrade products and how it gives producers in the developing world a fairer deal.
