Two prisoners serving life sentences who say rules which bar them from voting in the Scottish independence referendum breach their human rights have lost a fight in the UK's highest court.

The Supreme Court dismissed claims brought by Leslie Moohan and Andrew Gillon following a hearing in London.

Their claims had already been dismissed by judges in Scotland.

Supreme Court president Lord Neuberger told lawyers that the prisoners' appeals were dismissed after a day-long hearing. He said reasons would be given at a later date.

A panel of justices analysed provisions in the Scottish Independence Referendum (Franchise) Act 2013.

The panel considered whether provisions prohibiting prisoner voting were incompatible with the European Convention on Human Rights and if they breached the common law right to vote.
