Natalie Bennett: Why we want a referendum on Europe

Natalie Bennett, leader of the Green Party, explained to the BBC's Andrew Marr why she is in favour of an EU referendum.

"We believe in democracy," she said. "We want an EU that works for communities... not centralised in Brussels... making decisions at the right levels."

She also said that the Greens would not enter a coalition, but could support another party in government under a "confidence and supply" arrangement.
