Top EU officials warned on Thursday that the next Commission will lack in women, unless more governments put forward female candidates for the Commissioner posts.

The Education Commissioner urged designate President Jean-Claude Juncker to appoint at least 10 women in his future new team. Currently, 9 out of 28 commissioners are women.

“So we decided and we are now in the course of drafting a letter to be signed by all female commissioners addressed to the President designate Jean-Claude Juncker asking him to appoint at least 10 women in the next Commission I think this will be great for the new Commission.” said EU Commissioner for Education, Culture, Multilingualism and Youth Androulla Vassiliou.

In an attempt to persuade national governments, Juncker promised on Wednesday to reward countries who appoint female candidates with a big portfolio or vice-presidency.

So far, a few women’s names are circulating but none are confirmed. The Italian foreign affairs minister or the current Danish prime minister are among those names.

“The female Commissioners are very worried that the next Commission may not have sufficient number of women.” Vassiliou added.

President-designate Juncker will start discussions with governments on future commissioners and the distribution of portfolios next week, when EU leaders are due to meet in Brussels for a Council Summit on Wednesday.

Juncker is set to officially become the President of the European Commission next Tuesday after the European Parliament confirms him in a vote.
