The Green Party is urging voters to "vote big, vote brave" in a national billboard campaign launched by leader Natalie Bennett and Brighton Pavilion candidate Caroline Lucas.

Ms Bennett said: "The time for half measures is over. This country desperately needs bold changes to take us away from business-as-usual politics.Our message is clear: don't vote for second best, vote for what you believe in."

Ms Lucas added: "We have a bold message that will resonate with the people of Brighton and Hove, and across the country.

"Only the Green Party is willing to stand up to the establishment parties on issues like climate change, a resilient economy and protecting the NHS."
