World leaders welcome Rishi Sunak as new UK PM

Rishi Sunak on Tuesday became Britain's third prime minister this year and the first person of colour to hold the top job, receiving a flurry of welcome messages from around the world.

Here is how global leaders reacted:

Zelensky wants strong partnership

Ukrainian President Volodymyr Zelensky wrote on social media that he hoped Sunak would be able "to successfully overcome all the challenges facing British society and the whole world today".

He added that he was "ready to continue strengthening the Ukrainian-British strategic partnership", following months with London as one of Kyiv's most vocal supporters against Russia's February invasion.

Tackling challenges' with France

France's Emmanuel Macron tweeted that "together we will continue working to tackle the challenges of the moment, including the war in Ukraine and its many consequences for Europe and the world".

Italy is 'eager' to cooperate

From Italy, newly-installed Prime Minister Giorgia Meloni said that she was "eager to cooperate with (Sunak) and his cabinet on the common challenges, standing for our shared values of freedom and democracy."

Close friends' with Germany

"I look forward to our further cooperation and partnership in Nato and (the) G7 as close friends," German Chancellor Olaf Scholz tweeted.

Poland wishes 'success'

Polish President Andrzej Duda wrote that he was "looking forward to our meeting and cooperation and wish you success in your endeavours".

"Poland and the UK are steadfast allies and are standing together against the Russian invasion of Ukraine," he added.

'Strengthening ties' with Spain

From Spain, Prime Minster Pedro Sanchez said that "we will continue to strengthen our ties for the benefit of our fellow citizens. Only solidarity and unity will allow us to confront the challenges and consequences of the war in Ukraine".

Positive EU-UK relations

Maros Sefcovic, the European Union's point man on post-Brexit ties with Britain, said that "a positive EU-UK relationship is of strategic importance".

He vowed to work towards "a partnership in full respect of our agreements" - including the contentious issue of British province Northern Ireland's land border with EU-member Ireland.

European Commission chief Ursula von der Leyen said that "in these testing times for our continent, we count on a strong relationship with the UK to defend our common values".

Russia sees no hope for improvement

Kremlin spokesman Dmitry Peskov said that in Moscow, "we do not see any preconditions, grounds, or hope that in the foreseeable future there will be any positive changes" in the relationship between the United Kingdom and Russia.

Nigeria welcomes 'milestones'

Nigerian President Muhammadu Buhari said that with Sunak "as the first Prime Minister of British-Asian descent and the youngest in about 200 years, these milestones will be especially inspiring for young people" in the Commonwealth, the association mostly of former British colonies.
