On 19 June 2012, Ryanair Chief Executive Michael O'Leary announced his intentions to make an all-cash offer to buy Aer Lingus. However, the bid is likely to face a stiff challenge from the European Commission, which blocked an earlier 2007 bid. The combined companies would control 80% of the 370,000 journeys between the UK and Ireland every month. The Irish government said it was looking to sell its 25% stake in Aer Lingus; however, it was made clear that they would not sell their share to Ryanair due to competition concerns. Michael O'Leary pledged that he would keep the two airlines separate and competitive to one another. In 2015, IAG purchased Ryanair's shareholding in Aer Lingus, ending Ryanair's attempts to buy its oldest competitor.
