A delegate represents a country or NGO in a committee. The delegate is supposed to be aware of the issues debated in its committee and it is necessary to know his/her country or NGO’s specific attitude towards those issues. This means that the delegate must have researched his/her country and the issues before coming to the conference. Every country has one delegate in each forum in which it participates. An exception is the Security Council, in which there may be two delegates representing a country.
During the conference, the delegate should first lobby with the other delegates in his/her committee, to exchange the country's views and opinions. While lobbying, you can find out which countries agree with your own country's views. At this point resolutions can be improved or merged (which is combining two resolutions into a better one). After lobbying, formal debate will start, where the resolutions will be officially discussed.
