UK: Air traffic chaos, Foreign Secretary in China, Nadine Dorries finally resigns

UK correspondent Dan Bloom joins Kathryn to look at the flight chaos in the UK after an air traffic control glitch caused the cancellation of thousands of flights. He'll also talk about James Cleverly's visit to China - it's the first visit by a Foreign Secretary in five years and comes amid mounting frustration among many Tory MPs that the government's policy on China is too soft. And the Mid-Bedfordshire by-election will finally be held after Boris Johnson-ally Nadine Dorries kept her promise to resign...months late. Could the safe Tory seat fall to the opposition - and in that case, which one? The battle is on between Labour and the Lib Dems. Dan Bloom is deputy editor of Politico London Playbook
