In 2008, the Dutch conglomerate was pumped €10bn by the government on the condition of scale down its operations such as WestlandUtrecht and ING Direct in the US and bifurcate its bank and insurance operations.

The firm said that it was "reviewing strategic options" for the two units and added that the reviews do not necessarily mean that it involved any monetary transaction. The bank has not taken any decisions on how it would proceed.

ING Direct Canada has been serving 1.8 million since its inception in 1997, while the UK direct banking platform has 1.5 million customers and provides savings and mortgage products.

According to industry sources, the group has hired JPMorgan to find out the feasible way to dispose its Canadian unit and Credit Suisse to check viable options for the UK unit.

ING is also considering offloading or refinancing of its Japanese businesses and Asian insurance operations, which are valued nearly $7bn.
