4 February 2014 Last updated at 22:37 GMT

Oil giant BP boss Bob Dudley has warned there are "big uncertainties" for the company over the possibility of Scotland becoming independent.

Mr Dudley told the BBC the "question mark" over which currency Scotland might adopt if there was a 'yes' vote in September's referendum was "a concern".

Mr Dudley's comments have been dismissed by pro-independence campaigners, who say there are other energy firms who do not take the same view.
