The new Welsh Lib Dem leader Jane Dodds speaks following her by-election victory and calls for Boris Johnson to act on the climate crisis and rule out no-deal Brexit. The Liberal Democrats won the mid-Wales constituency by a margin of 1,425, swinging the vote nearly 12% from the Tories. Mr Johnson's first major challenge as Tory leader became his first major defeat with the announcement of Jane Dodds' victory in the early hours of Friday. The Tory loss will add to the PM's challenges to steer Brexit through Parliament and may increase the chances of a snap general election. With the vote coming eight days after Mr Johnson was anointed, it is the quickest by-election defeat for any PM of the post-War period.
