Greens call for urgent inquiry into East Sussex chemical cloud

Authorities say mysterious haze that left 150 people requiring medical treatment is unlikely to have come from France

The Green party has called for an urgent investigation into the chemical cloud that closed beaches across East Sussex on Sunday.

Caroline Lucas, the party's co-leader and MP for Brighton Pavilion, said an inquiry was needed to determine "how this gas came to be in our atmosphere and engulfing our beaches, and an action plan put in place to ensure this never happens again".
