Nicola Sturgeon will launch the Scottish National Party's manifesto later with an attack on Prime Minister Boris Johnson as "dangerous and unfit for office". Calling his Brexit deal a "nightmare" for Scotland, Ms Sturgeon will say only the SNP offers a chance to "escape Brexit and put Scotland's future in Scotland's hands". The party - the third-biggest in Parliament after the 2017 election - hopes to have the balance of power, and the chance to force another Scottish independence referendum, if no party wins a majority this time around. Mr Johnson has ruled out giving consent for another public vote if he remains prime minister.
Jeremy Corbyn will be back on the campaign trail after admitting in a BBC interview that Labour's plans to scrap a tax break worth up to £250 for married couples could result in some who earn less than £80,000 a year paying more tax. That's contrary to previous claims, although the Labour leader said those affected could benefit from a higher living wage and extended free nursery provision. Mr Corbyn also struggled to move on from claims of anti-Semitism within his party, says our political editor Laura Kuenssberg, on a day when the Muslim Council of Britain accused the Conservative Party of "denial, dismissal and deceit" over the issue of Islamophobia.
The Liberal Democrats say they would increase the minimum wage by 20% for zero-hour contract employees.

Donald Trump should either attend impeachment hearings in Congress that could result in him being removed from office, or "stop complaining about the process". That's the blunt message Jerrold Nadler, the Democratic chairman of the House Judiciary Committee, delivered alongside an invitation to the US president to attend and question witnesses on 4 December. Mr Trump has called the inquiry a "witch hunt" and denies breaking the law by pressuring Ukraine's leader to dig up damaging information on political rival Joe Biden.

Nato leaders are set to meet in London next week to mark the military alliance's 70th anniversary and some timely research from the Royal United Services Institute will give them food for thought. It imagines a "high-intensity conflict" with Russia in Eastern Europe, where 800 UK personnel are stationed as part of a Nato force, and says the British army and its allies would be hampered by a "critical shortage" of artillery and ammunition. The scenario might be unlikely, it acknowledges, but UK ground forces would be "comprehensively outgunned and outranged", leaving enemy artillery free to defeat UK units. In response, the Ministry of Defence says the UK "does not stand alone" and its armed forces are "well equipped to take a leading role in countering threats".

Several papers lead on Jeremy Corbyn's refusal to apologise over claims of anti-Semitism within the Labour Party during what the Times calls a "searching interview" on the BBC. Referring to his performance on The Andrew Neil Interviews, the Daily Express asks: "Has Corbyn horror show gifted Boris keys to No 10?" The Daily Mirror, however, focuses on the Conservatives, saying a trade minister has held "secret talks" with a US drug firm over a post-Brexit pact targeting the NHS. Others focus on a £105m Euromillions lottery jackpot, with the Sun re-naming winner Steve Thompson "worth a few bob the builder".
