By Kirstin Ridley LONDON (Reuters) - Former Barclays finance director Chris Lucas would have been criminally charged over two emergency fundraisings launched by the bank at the height of the financial crisis if he were not too ill to stand trial, a London fraud trial heard on Wednesday. As a former bank director, Lucas, who stepped down in 2013 due to his health, arguably took direct responsibility for false representations in the bank's public documents about capital raisings in June and October 2008, a prosecutor for the UK Serious Fraud Office (SFO) alleged.
