Newscast, Americast & Ukrainecast join together to mark the BBC's 100th birthday.

Rishi Sunak has called the UK General Election for the 4 July. Adam is joined by Laura Kuenssberg, Faisal Islam and Alex Forsyth to discuss the surprise announcement by the Prime Minister this afternoon.

​​Today, Laura is joined by Faisal Islam and James Cook to talk about what we can expect in manifestos this week, and how parties say they’ll pay for policies. ​​They chat about the Conservatives’ announcement on welfare spending, Labour’s plans to build more prisons and Nigel Farage’s response to Rishi Sunak’s D-Day blunder. And we ask why the SNP didn’t mention Scottish independence on Friday’s debate.

Today, we look at the Conservative manifesto launch as Rishi Suank promises a further cut in National Insurance. Unveiling the party’s plans from Silverstone race track, the PM said he would "scrap entirely the main rate of self-employed National Insurance” and that the Conservatives would "keep cutting taxes in the coming years”. Does this all add up? Adam and Chris are joined by BBC Economics Editor Faisal Islam and Newsnight Political Editor Nick Watt.
