Nathan Bostock, Chief Executive Officer, said:
"The UK economy improved during 2014 and will, we believe, continue to be supportive of our business in 2015. Progress on clarifying the regulatory landscape has been made and further details are expected in 2015, particularly in relation to capital, leverage, conduct and banking structure. Early completion of these reforms, in a proportionate way, will help us to contribute fully to UK’s ongoing economic recovery."
