Ahead of Cameron’s visit to Lebanon, tens of thousands of people marched in London Saturday to demand Britain do more to help refugees. Longtime anti-austerity, antiwar lawmaker Jeremy Corbyn spoke at the rally just after he was elected leader of the opposition Labour Party.

Jeremy Corbyn: “We, as ordinary, decent people, stand up and say to our government, 'Recognize your obligations in law — that would be good. Recognize your obligations to help people, which you're required to do by law — that would be good. But above all, open your hearts and open your minds and open your attitude toward supporting people who are desperate, who need somewhere safe to live, want to contribute to our society, and are human beings just like all of us.’”

When Corbyn first announced his candidacy three months ago, oddsmakers initially put his odds of winning at 200 to one. But on Saturday, Corbyn won in a landslide, receiving 59 percent of the vote to succeed Ed Miliband, who quit after the Conservatives retained power in May’s election. We’ll have more on Corbyn’s victory later in the broadcast. Meanwhile, tens of thousands more people rallied across Europe over the weekend to take part in what organizers were calling a “European Day of Action for Refugees.” Danish police say as many as 30,000 people had gathered in Copenhagen, shouting “Refugees are welcome.” In Italy, hundreds of people gathered at the Venice waterfront, removed their shoes and marched barefoot, as the Venice Film Festival was underway. Crowds also rallied in Spain, Ireland, Austria, Greece, Finland, Norway, Turkey, France and Iceland.
