Theresa May will meet President Donald Trump at Davos amid reports of strains on the so-called "special relationship" between Britain and the United States.
It is the first time both leaders have met since they clashed over Mr Trump's decision to share anti-Muslim videos tweeted by the deputy leader of the far-right group Britain First.
The Prime Minister will also use a speech at the World Economic Forum to urge investors to pull their funds from tech giants such as Facebook and Twitter if they fail to remove extremist material from their sites.
Meanwhile, Labour leader Jeremy Corbyn is set to host a Westminster rally demanding an emergency budget to help the NHS cope with the ongoing winter crisis.
