David Cameron launches the final phase of the Conservative local election campaign at the party's headquarters on Victoria Street in central London.
Also present are local government spokesman Eric Pickles, shadow environment secretary Peter Ainsworth and Caroline Spelman who shadows the office of the deputy prime minister.
Mr Cameron focused on environmental issues warning there was no bigger issue than global warming and that it was necessary for people to "think global, act local".
He also dismissed Labour's attacks on him claiming he was a chameleon changing his colours to suit his audience and stressed his campaign would be positive.
LEADER'S KEY QUOTES
Mr Cameron was launching the final phase of the local poll campaign
"If you want your local area to have more recycling, greener parks and public spaces, cleaner streets and better transport, vote Conservative on May 4. So the message is clear - Vote blue, Go green."
"I think it is actually important that political leaders take time to study the big challenges that face our country and our planet. And there is no bigger challenge than climate change."
Mr Cameron was keen to stress the positive aspects of his campaign, the fact he was taking questions and that he did not want to have a glitzy affair. He stressed this was about local issues and his frontbench team were out bolstering local campaigns.
