Barclays' investment bank, set to be revamped and resized under group chief executive Antony Jenkins, has signed off with a strong set of figures for the fourth quarter and 2012.

The UK bank published its fourth-quarter and full-year results for 2012 this morning in what was effectively an apéritif to a Jenkins presentation, slated for 10.30 GMT, on plans to overhaul the business and culture at Barclays following a wide-ranging strategic review.
