A new ‘unkillable’ weed impervious to even the strongest herbicide has been found in the UK for the first time.

Italian ryegrass has been growing in several fields on a farm in Kent.

Scientists have confirmed it is resistant to glyphosate, considered to be the most effective weedkiller on the market.

Weeds resistant to glyphosate have been discovered several times before – but this is the first time it has been found in Britain.
