MEP Influence Index 2024: Top MEPs shaping EU’s Foreign affairs, defense & enlargement

This analysis measures the influence that Members of the European Parliament are exerting over EU legislation and documents that shape EU foreign affairs, defence & security policy. It is part of a series of reports that includes:

This research measures MEPs’ influence through a combination of criteria clustered in the following categories: formal and informal leadership positions, actual legislative work, political network, committee membership and voting behavior. 

Disclaimer: this is an assessment based on our team's 15+ years of experience in interpreting relevant EU socio-political data. The aim of this research is not to provide an "absolute truth", but rather to provide an indicative overview. As in any such research, the weighing of the criteria may contain an intrinsic degree of subjectivity, which we aimed to reduce by consulting with a wide range of analysts and practitioners.To read the full methodology, click here.


Key findings:

  • The top most influential MEPs on foreign affairs, defense & security have been: Tonino Picula (S&D AFET Coordinator and active on reports such as the EU strategy for enlargement), David McAllister (Chair of AFET and rapporteur on various files regarding EU’s external relations and security), Hilde Vautmans (Renew AFET Coordinator and active on various reports with special regard to EU-China relations), Petras Auštrevičius (Renew SEDE Coordinator and active legislator with special attention on Eastern European neighbours) and Nacho Sánchez Amor (S&D DROI Coordinator and active legislator especially on human right issues). See the full top 10 below.
  • Renew and S&D proportionally outperform EPP members, while delegations from the Baltic and Balkan regions tend to be punching above their weight when it comes to influencing this policy area. See the full stats below.

More details on the above findings can be found below.


Important: when tracking influence over EU policies, always bear in mind that while individual MEPs are the visible signatories of initiatives or amendments, they are not operating in an information vacuum. Rather, their views and actions are shaped by a wide range of political and societal stakeholders that engage with them.

To understand the full picture, you need to look at the strength of these forces and the direction in which they are pushing and pulling. For example, the chart below shows the level of influence of all MEPs on foreign affairs, defence and security issues, but also the direction in which each of them is working to influence the debate on EU defence, e.g. whether they promote a stronger focus on the defence integration or they are opponents of the defence integration. Particular attention should be paid to the MEPs who are in the middle, i.e. which have both a fair level of influence and their views are moderate, because in the current (and future) fragmented political landscape, these MEPs (the swing voters) are the ones that make the difference, i.e. their votes are the ones that decide whether a key paragraph is approved or not.

Note: the positions of the MEPs in the chart below on the horizontal axis is based on an assessment of their voting behavior on a wide range of paragraphs and amendments on this particular sector.

The visual below shows our assessment of the most influential 10 MEPs in this sector (scroll to the right to see the full list).

The list is also available as a table format here.

NB: at least 3 of these top 10 MEPs are likely to come back after the elections. Would you like to know which ones? Contact us at [email protected] for more information on our EP2024 elections info-pack (which includes likely MEPs, Commissioners, policy impact, and much more). 


In addition to the top 10 most influential MEPs, we have found it interesting to identify the MEPs from each group that has had the most "personalised" views (i.e. different from those of their political group), on either side of the debate. In other words, who is the most to the right and to the left of their political group on this chart. This is based on the analysis of their voting behavior on a wide range of relevant paragraphs and amendments impacting on this sector. These findings are represented below.



Trends by political group 

Although this policy area is often seen as one of the EPP “strong” topics, members of S&D and Renew groups are proportionally more influential on this policy area compared to the MEPs from the EPP. S&D is also the group more strongly represented in our list of top 10 influencers. 



Trends by country

Perhaps, unsurprisingly, MEPs from Baltic countries such as Estonia and Lithuania are, on average, the most influential on foreign affairs, defence & enlargement files. Also the delegations with a strong involvement in the Balkans, such as Austrians, Slovenians, Croatians, Bulgarians are very active on foreign affairs and enlargement issues. 

Delegations from other regions are also punching above their weight, although their focus is likely to be different, as in the case of the Spanish and Portuguese.
