A total of 22 committees currently exist. 20 permanent main committees and 2 subcommittees. Further special committees or subcommittees can be set up to cover other topics by the European Parliament.
A committee consists of a number of members of the European Parliament, with the current numbers going from 24 in PECH (fisheries) to 76 in AFET (foreign affairs). It has a distribution in group-affiliation matching the parliament as a whole.
The committees deal with European Commission and Council proposals as well as writing their own opinions. In the ordinary legislative procedure they propose amendments and recommandations on if they believe the European Parliament as a whole should reject or accept a proposal and why. In each matter the president of the European Parliament, along with the leaders of the political groups and a member of parliament with no formal group choose a lead committee among the relevant committees to report on the specific issue. Each of the committees elect a member among them to act as a rapporteur or – for opinions – draftsperson. This person is responsible for writing a draft for a report/opinion for the plenary to use in votes. While work is ongoing in the committee there can be held hearings with specialists and experts as well as the European Commission can give their opinions, debates among the members of the committees and votes on amendments to reports/opinions.
During negotiation with the Council and European Commission the lead committee has the responsibility to set a negotiation team from the European Parliament. The team consists of representation from each group in the European Parliament. When negotiating the team has a responsibility to act according to amendments made by the European Parliament in plenary and in the committees.
