Rishi Sunak, was, this Tuesday, appointed British Prime Minister by King Charles III. In his first address to the nation, he promised to "unite the country not with words but with deeds."

The UK's new prime minister, Rishi Sunak, said Tuesday that he had "accepted the request" of King Charles III to "form a new government. In his first speech to the country, the ruler acknowledged that "some mistakes" were made by his predecessor, Liz Truss.

"Some mistakes were made. Not because of bad intentions. I was elected party leader and your prime minister, in part, to correct them and that work begins immediately," he stressed.

Sunak said that the UK faces a "deep economic crisis" due to the Covid-19 pandemic and the impact of the war in Ukraine on financial markets.

The new British leader also recalled his position as finance minister during Boris Johnson's tenure. "You saw me during Covid-19 doing everything I could to protect people and businesses," he stressed. "There are always limits, now more than ever. But I promise you this: I will bring that same compassion to the challenges we face today."

And he left a promise to the UK: "The government I lead will not leave the next generation, your children and grandchildren, with a debt to pay off because we were too weak to pay ourselves. I will unite our country not with words, but with actions."

Sunak said he will be "forever grateful to Boris Johnson for his incredible achievements as prime minister," but warned that the majority won by the former prime minister in 2019 "is not the sole property of any individual."

"It is a mandate that belongs to us and unites us all. That mandate is our manifesto," he said adding that he will deliver on what was promised by Boris Johnson, especially building an economy that "embraces the opportunities of Brexit."

The new leader of the Conservative Party, Rishi Sunak, was this morning appointed prime minister of the United Kingdom by King Charles III.

King Charles III has accepted Liz Truss' resignation. According to a statement, published by Buckingham Palace, "The Right Honourable Elizabeth Truss had an audience with the King this morning and tendered her resignation as Prime Minister, which His Majesty was pleased to accept graciously."

The former prime minister bid farewell to the nation this morning in a speech that was marked by the need to be "bold" to "face challenges." "As the Roman philosopher Seneca wrote, it is not because things are difficult that we do not dare, it is because we do not dare that they are difficult. From this time as prime minister, I have become more convinced than ever that we need to be bold and face challenges," she said.

Liz Truss announced on Thursday that she has tendered her resignation to King Charles III. "I recognize that, given the situation, I cannot fulfill the mandate to which I was elected by the Conservative Party. I have therefore spoken to His Majesty the King to notify him that I am resigning as leader of the Conservative Party," she said in a statement outside the official Downing Street residence in London.
