Salmond's legal threat

So let's be clear about this...

- There will be separate debates in Wales and Scotland featuring Plaid and the SNP as appropriate;

- The SNP will not be running enough candidates UK-wide to have a chance of forming a Government;

- Alex Salmond is not even going to be a candidate at the General Election

And yet Mr Salmond is still thinking about taking legal action in order to secure himself a space in the UK wide leaders' debates.

Is this a case of ego above reason?
