UK freight operator MK Airlines has voluntarily handed in its air operator's certificate and ceased operations.

A spokeswoman for the UK CAA confirms that the carrier returned its AOC "in the early hours of this morning", but declines to provide further details.

Forwarding and logistics firm Panalpina Group said last week that MK was "temporarily" halting services "due to a lack of adequate resources".

MK went into administration in June 2008 but emerged just over a year later. The UK-based carrier has a fleet of Boeing 747-200 and McDonnell Douglas DC-8 freighters.

MK Airlines could not immediately be reached for comment.
