Election 2015: The view from island of Anglesey
In Wales, Plaid Cymru is hoping to benefit from the higher public profile it has enjoyed during the election campaign, with its leader taking part in televised debates seen across the UK.

Labour's support in Wales looks strong, too; far healthier than it does in Scotland.
But there are some key battles between Labour and Plaid Cymru.
Huw Edwards has been to Ynys Mon, Anglesey, one of the heartlands of Welsh-speaking Wales, to talk to the island's voters about their priorities.
