UK Prime Minister Theresa May said “it is time to say enough is enough”, condemning a terror attack on civilians in London which left seven dead and 48 injured. A van hit pedestrians on London Bridge on Saturday night; three men got out and stabbed people at Borough Market. These men were shot dead by police; several arrests have been made since, in east London. This is the third terror attack in the UK in three months. Mrs May said there has been “too much tolerance of extremism in our country”; while it would involve “some difficult and embarrassing conversations”, this must change.

Leo Varadkar won the race to replace Enda Kenny as the leader of the Fine Gael party in the Irish Republic. Mr Varadkar’s election made international headlines due to his background, age and sexuality; the son of an Irish mother and Indian immigrant father, he will become the youngest ever Taoiseach (aged 38) and the country’s first gay leader. After beating Housing Minister Simon Coveney in the leadership contest, Mr Varadkar said: “If my election shows anything it’s that prejudice has no hold in this Republic.”

DUP leader Arlene Foster said maintaining the union with the UK is the most important issue in Thursday’s general election. Launching her party’s manifesto, she said returning a majority of unionist MPs would end the idea of a border poll for generations. At the SDLP’s manifesto launch, leader Colum Eastwood called for a referendum on Irish unity after Brexit negotiations conclude; Sinn Féin has said it wants a border poll within five years. The UUP launched its manifesto; leader Robin Swann rejected calls for Northern Ireland to be granted special status by the EU after Brexit; those seeking this, he said, wish to create a “united Ireland by the back door.”

Theresa May and Labour Party leader Jeremy Corbyn joined a BBC Question Time election special. In separate sessions, both leaders took questions from audience members. Mrs May warned that Mr Corbyn would only become PM by being “propped up” by the Lib Dems and Scottish Nationalist Party; Mr Corbyn denied this, saying there would be no such deals. Mrs May has refused to debate Mr Corbyn head-to-head throughout the campaign; in a leaders’ debate held earlier in the week, Home Secretary Amber Rudd took Mrs May’s place whilst all other main party leaders, including Mr Corbyn, participated.

US President Donald Trump announced America will withdraw from the Paris climate change agreement. This deal commits countries to keeping rising global temperatures “well below” 2C (3.6F) above pre-industrial levels and “endeavour to limit” them further, to 1.5C. Mr Trump’s decision – he said the deal would hurt the US economy – attracted widespread condemnation. Only Syria and Nicaragua failed to sign the agreement; they believed the accords do not go far enough. During Mr Trump’s election campaign, he claimed climate change was a hoax.
