Independence talks between First Minister Alex Salmond and Prime Minister David Cameron held last week in Edinburgh drew a blank after the leaders disagreed on the date and practical issues of a potential referendum.

Cameron started the day by giving a speech in the Apex International Hotel in the Grassmarket, before a view of Edinburgh Castle, during which he made his case for Scotland continuing to be part of the United Kingdom.

He said, “whether in Edinburgh or London, the United Kingdom is a warm and stable home that millions envy. In an increasingly competitive world the future belongs to those who can cooperate or collaborate best.

“I come here today with one simple message: I hope and wish that Scotland votes to remain part of the United Kingdom.

“I believe that England, Scotland, Wales and Northern Ireland are stronger together then they ever would be apart. It is time to speak out, whatever the consequences, because something very special is in danger.”

Whilst the SNP have said in the past they aim to hold a referendum in 2014, Cameron has indicated that he would favour an earlier vote.

If the referendum was held in 2014, it would coincide with the 700th anniversary of the Battle of Bannockburn.

The two ministers later held talks inside St Andrew’s House on Calton Hill.

Despite indicating that the talks had been congenial, Salmond was unimpressed and he told the BBC, “the Prime Minister should trust the Scottish Parliament and the Scottish people to organise their own referendum, it is after all, about Scotland’s future.

“We are perfectly capable of organising a proper and democratic referendum and I think the Prime Minister should allow us to do that.

“What we’re used to hearing from the London parties is a stream of negativity, so I welcome the fact that the Prime Minister has considered the viability of an independent Scotland.”

Cameron’s visit was not unimpeded, however. Around 30 anti-cuts activists gathered outside the Apex Hotel and later at Calton Hill in an impromptu protest against the coalition government’s austerity programme.

Two students from the University of Edinburgh were arrested and were due to appear at Edinburgh Sheriff Court last Friday.
