The World Tonight

Allegations of 'family voting' in the Gorton and Denton by-election are to be raised in parliament on Monday. We speak to Lord Pickles, whose report into electoral fraud called for action a decade ago. We also look at where the by-election leaves Labour strategy: are Reform or the Greens their main opposition now? Also:Bill Clinton testifies in front of a Congressional committee; President Trump says he's "not happy" as concerns grow about a possible US attack. And 30 years of Pokemon.
