This could be a new beginning for British foreign policy -- and the UK can have a huge effect on the global issues like, climate change, global poverty, and more.

Miliband promises "A New Diplomacy", and wants to get off on the right foot by engaging global public opinion. Do you have a question for the new British foreign affairs chief? A statement, piece of advice, warning or encouragement? Avaaz will ask members' questions to him after his speech, and compile your words of advice into a book that he will keep in his office and consult when looking for the views of people around the world. Click here now to contribute a question or comment.

Miliband is asking himself some questions too: what Britain's foreign priorities should be, how to be more multilateral. Avaaz is also hoping that some members will submit their questions via video - it would be particularly powerful for our members from the Middle East, Asia or Africa to ask questions by video. (Just email comments@avaaz.org for help if you need it.) And a webcast of the whole event will be on their site after Thursday.

The best time to influence a government is in its first few days in power. If we are to make the views and values of the world's people shape global decisions, we need to engage openly and honestly with the people who decide. This is a great opportunity for the community to do just that.

So let's test the waters -- and give this Foreign Secretary some food for thought.

PS If you want to post a video question, YouTube is the best way - you can just use your computer's webcam at this link.
