This means that on issues such as sanctions against Russia, one country can block agreement, as happened last summer when Slovakian Prime Minister Robert Fico vetoed a package of EU measures against Moscow — a veto that was eventually lifted. Such power in one country’s hands is something that the EPP would like to change. 

As for military solidarity, Article 42.7 of the Lisbon Treaty obliges countries to provide “aid and assistance by all the means in their power” if an EU country is attacked. For Weber, the formulation under European law is stronger than NATO’s Article 5 collective defense commitment.

However, he stressed that the EU still lacks a clear operational plan for how the clause would work in practice. Article 42.7 was previously used when France requested that other EU countries make additional contributions to the fight against terrorism, following the Paris terrorist attacks in November 2015. 

Such ideas were presented as the party with a biggest grouping in the European Parliament — and therefore the power to shape EU political priorities — presented its strategic focus for 2026, with competitiveness as its main priority. 

The EPP wants to unleash the bloc’s competitiveness through further cutting red tape, “completing” the EU single market, diversifying supply chains, protecting economic independence and security and promoting innovation including in AI, chips and biotech, among other actions, according to its list 2026 priorities unveiled on Saturday.

On defense, the EPP is pushing for a “360-degree” security approach to safeguard Europe against growing geopolitical threats, “addressing state and non-state threats from all directions,” according to the document.
