Clydesdale Bank is a member of National Australia Bank (NAB), which has over 12.7 million customers internationally. Founded in Glasgow in 1838, Clydesdale Bank was purchased by Midland Bank in 1920. It was later sold to NAB in 1987 and now has around 4,500 staff and over 150 branches. Yorkshire Bank, NAB's other British subsidiary, operates as a division of Clydesdale under its banking licence.
For the six months ended 31 March 2015, Clydesdale Bank posted a pre-tax profit of £113m, up from £87m a year ago.
In May 2015, NAB announced that it has decided to demerge Clydesdale by the end of the year. It is expected that the majority of shares will be offered to existing shareholders and the remainder will be sold to institutional investors.
David Duffy, the former Allied Irish Bank chief, joined Clydesdale Bank as chief executive officer, replacing David Thorburn, with effect from Friday 5 June 2015.
