Losses for UK Labour as polls test Jeremy Corbyn's leadership

UK Labour has suffered a drubbing in Scotland and setbacks south of the border in elections seen as the first nationwide verdict on Jeremy Corbyn's leadership of the party.

Scottish Conservative leader Ruth Davidson made clear she expected to head the main opposition party at Holyrood as Labour looked set to slump into third place in Scottish Parliament polls, losing more than nine points in its share of the vote.
