Russia has been making some advances in Ukraine against Kyiv's weakened and outgunned forces, with Moscow regularly claiming the capture of more eastern villages.

The gains followed months of delays in new US funding for Ukraine linked to protests by right-wing members of the US Congress. European Parliament elections in June meanwhile saw a shift to the right among voters.

"Ukraine's determination to fight and European support for arming Ukraine have not been affected by Russian advances on the battlefield," the European Council on Foreign Relations (ECFR) said in a new survey.

This report was based on public opinion polls conducted across 15 European countries, including Ukraine, and relied on feedback from nearly 20,000 respondents.

"In most countries, a majority (or, at least, a significant plurality) of citizens supports the idea of increasing the supply of weapons and ammunition to Ukraine," the council noted.

And while support for Ukraine's fight against Russia remained mostly steady across Europe, most respondents were more lacklustre about Kyiv's chances of winning.

"In short, Ukrainians want weapons in order to win, while most Europeans send weapons hoping this will help lead to an acceptable eventual settlement," said the report.

Kyiv has long insisted on regaining all of the territory seized by Russia as a prerequisite for ending the war.

The vast majority of Ukrainians remain opposed to the idea of ceding territories to Russia in exchange for NATO membership, according to the report.

"The prevailing view in most countries (except for Estonia) is that the conflict will conclude with a compromise settlement," ECFR noted.

The study reveals most people in Estonia, Poland, and Sweden -- among Kyiv's most ardent supporters -- want to help Ukraine fight to regain its occupied territories.

But people in countries such as Bulgaria, Greece and Italy are among the most sceptical that Ukraine can prevail on the battlefield, even if arms supplies increased.

In the middle of these positions are countries including Czech Republic, France, Germany, the Netherlands, Spain, and Switzerland, "which are still struggling to consolidate a national consensus on the war and the EU's role therein".
