Eu welcomes boris johnson victory
I think there may be some confusion here!
The European Union (EU) is a political and economic union of 27 member states, and it does not have the ability to "welcome" or make statements about the outcome of elections in individual member states.
However, I can provide some context.
Boris Johnson is the current Prime Minister of the United Kingdom (UK), and he led the Conservative Party to a majority in the 2019 UK general election. The UK is a member of the EU, but it has been in the process of leaving the EU (Brexit) since 2016.
The EU has been involved in the Brexit negotiations with the UK, and the two sides have been working to agree on the terms of the UK's withdrawal from the EU. The EU has been seeking to ensure a smooth transition and maintain good relations with the UK, while also protecting its own interests and the interests of its member states.
In this context, it's unlikely that the EU would make a public statement "welcoming" Boris Johnson's victory, as the EU's focus is on the Brexit negotiations and maintaining good relations with the UK, rather than taking a political stance on the outcome of individual elections.
