Labour have promised to renationalise nearly all passenger railways within their first term if they win the next election. But will it leave the railways better off?   On the Sky News Daily, Niall Paterson speaks to Sky's political correspondent Sam Coates to discuss the details of Labour's plan and assess if a Great British Railway would be more efficient and cost-effective than the current privatised system.  Niall also speaks to the editor of Rail magazine, Nigel Harris, to discuss the current state of our railways and what he believes needs to change.    Elsewhere in politics, the Scottish government has ended its power-sharing agreement with the Greens. Sky's Scotland correspondent Connor Gillies discusses the implications of this for both parties – including a motion of no confidence in First Minister Humza Yousaf.    Producers: Iona Brunker, Soila Apparicio, Emma Rae Woodhouse  Editor: Paul Stanworth
