Plastic straw and cotton bud ban proposed

Plastic straws and cotton buds could be banned in England as part of the government's bid to cut plastic waste.
Announcing a consultation on a possible ban ministers said 8.5bn plastic straws were thrown away in the UK every year.
The prime minister said plastic waste was "one of the greatest environmental challenges facing the world".
And Theresa May will urge leaders at the Commonwealth Heads of Government Meeting, which starts later, to follow the UK's lead in tackling the problem.
The Queen will formally open the summit at an event at Buckingham Palace attended by prime ministers and presidents from the 53 states that make up the organisation.
