DUBAI- First Abu Dhabi Bank's head of corporate finance, Andy Cairns, is leaving United Arab Emirates' biggest lender, a source close to the matter said.

Cairns, a senior managing director at FAB, had been with the group for eight years.

It was not immediately clear why he is leaving the bank.

FAB did not immediately respond to a Reuters request for comment.

FAB has emerged as a major player in the loans and bonds market in the Middle East and North Africa and has been involved in major regional transactions.

It was among the lenders in the $10.5 billion loan deal to finance Saudi Aramco's sale of oil pipelines to a consortium led by Washington DC-based energy infrastructure investor EIG.

FAB is also among the banks advising Abu Dhabi National Oil Co (ADNOC) on the listing of its drilling business.

Cairns in the past also worked with Bank of America Merrill Lynch and HSBC, his Linkedin profile shows.
