executive trio leave aer lingus three senior executives of ireland s state-owned airline  aer lingus  are set to leave early on 28 january after accusations of a conflict of interest.  the trio are chief executive willie walsh  chief financial officer brian dunne and chief operations officer seamus kearney. the three have refused to confirm reports they plan to launch a private airline in competition with aer lingus. they announced in november they would quit in may  but did not give a reason. that decision had followed an announcement by irish prime minister bertie ahern - who is still considering the future of the airline - which ruled out a proposed management buy-out of aer lingus. mr walsh denied they had been forced out early because of the reports claiming they were set to launch a competitor airline.   what i do after i leave aer lingus is still too early to say   mr walsh told ap news agency on wednesday.  i have opportunities open to me. brian and seamus are in the equally fortunate position.  he said he had received more than 40 business proposals  mostly aviation-related  since the trio announced their resignations two months ago. mr walsh said there was no conflict of interest  and  if he was to launch a rival airline or join an existing competitor   this thing happens in every business .  there s absolutely no question of a conflict of interest. i ve been completely focused on my responsibilities at aer lingus   he told ap.  this week opposition politicians had called on the irish government to make an urgent decision on the future of the airline. on wednesday irish transport minister martin cullen said in a statement:  a conflict of interest cannot  should not and will not be allowed to arise between their current roles at aer lingus and their future career intentions.  last friday the minister had announced he was to advertise for three senior executives for aer lingus. mr walsh  who took charge in 2000  and his team have earned praise for turning aer lingus around  by cutting air fares and staff  and re-positioning it as a low-fare airline to rival ryanair. the company is 85% owned by the government and 15% by its staff.
