Russia struggles to stabilise the four regions of Ukraine whose annexation was formalised this week. We ask Ivanna Klympush-Tsintsadze whether Kyiv can retake land. Rhys James walks us through a fractured Britain, Tom Webb has a creative approach to get workers back into the office, Laura Kramer speaks to film-maker Saim Sadiq about his collaboration with Malala Yousufzai and Jack Simpson takes a look at the winners of this year’s Nobel Peace Prize . Plus: our weekly Letter From New York.
