OPINION: Seven of the UK's major supermarket chains have now responded to the call for them to back the nation's farmers by adding 'buy British' tabs to their websites.
Tesco is the latest to join the campaign, which the National Farmers Union have been pushing for.
The move follows an open letter written by Conservative MP Dr Luke Evans to the CEOs of eight major supermarkets, asking for a filter which would direct online shoppers to home-grown food to help "boost the economy and cut the UK's carbon footprint".
The letter was co-signed by 126 cross-party MPs, none of whom seem to realise that UK produce is likely to have a higher carbon footprint than food imports, such as NZ lamb, which Lincoln University has proved can be shipped around the world and landed in the UK with a lower carbon footprint than the local product!
