London Irish

London Irish was the third club to be formed in England by working and student exiles from the home countries, following London Scottish in 1878, London Welsh in 1885; followed by London Cornish in 1962. The first game took place on 1 October 1898 against the former Hammersmith club at Herne Hill Athletic Ground, with London Irish winning 8–3. The team that season benefited from the early recruitment of vet and Irish international Louis Magee. He became essential in the early years of the club along with club captain R.S Dyas in putting the team on the map and having regular fixtures between other London-based teams.

The turn of the new century was a great time for London Irish with the club firmly solidified in the London club roster but these would be some of the last years of normality for the team. With the commencement of World War I, many of the players enlisted with Irish Battalions in their homeland for deployment in mainland Europe. In 1916, following the Easter Rising, a number of remaining players and members returned to Ireland to fight in the independence struggle; many did not return. It is unknown exactly how many with a connection to the club were lost. Following the formation of the Irish Free State in 1923, some of those who fought in Europe and/or Ireland returned to the club, which saw an overhaul of the organisation over the remainder of the decade, reviving the team and its influence for a new beginning.

In the years that followed, Irish made strides in playing competition outside of Greater London with matches against teams such as Leicester and Cardiff. This, however, was short-lived with the commencement of World War II and players and members again being dispersed across the continent, many of whom elected not to return following the end of the war. Nine of the players who participated in the 1938–39 season died in the conflict. The club's then playing ground located in Sunbury-on-Thames was acquired by Ministry for Agriculture to be used as a site to grow food for the war-torn capital. Because of the state of the playing field after the war, games were temporarily held at Rectory Field in Blackheath.

The post-war era got off to a rocky beginning. Player numbers weren't what they used to be as former members elected not to move back to London and this made it difficult to front a starting XV. The year that followed saw the Winter of 1946, one of the coldest winters on record in the United Kingdom. Rectory Field was frozen for most of the winter meaning Irish missed matches in the season. Things picked up with the arrival of a new captain, Des O'Brien, and a number of other key players and in 1948 London Irish celebrated their 50th anniversary with the most successful season yet for the club.

In the 1950s the club thrived, fielding teams most weeks, and in 1951 they became the first club to host touring Italian team Roma. On 9 September 1959, Irish returned to Sunbury and had a place to call home, which was dubbed The Avenue. They achieved a record-breaking season, remaining unbeaten.

Results in the 1960s were mixed, with many good wins but also a number of defeats. Fixtures improved and the club played against many famous teams, which changed the attitude of the training and playing and, in the 70s, London Irish became a force to be reckoned with, finishing first in the London Division of the Rugby Football Union in the 1976–77 season. Pre-season tours became popular and in 1977, the London Irish made history in South Africa when they became the first touring side to play a host of mixed-race teams.

Since the professional era began in August 1995, London Irish has only lifted one piece of major silverware, winning the Powergen Cup in 2002 in a match against Northampton at Twickenham that saw the club win 38–7. Some 75,000 people attended the match, seeing the Exiles win in what is regarded as one of the most successful days in the club's history. London Irish enjoyed success in Europe in 2005–06 when they reached the final of the Challenge Cup, only to be defeated by Gloucester 36–34 at Twickenham.

In 2013, Irish were taken over by a consortium led by Mick Crossan, executive chairman of Powerday, a London-based recycling and waste management firm. Powerday would go on to be one of the club's main sponsors.

In early May 2023, the RFU sought clarification from London Irish about why the club's players and staff had not yet been paid for April 2023. On 15 May the RFU gave the club a 30 May deadline to sell the club to new owners, and indicated the club would be suspended from the Premiership if they were not satisfied the club had sufficient funding. Two weeks later, the RFU extended the deadline until 6 June.

On 2 June 2023, London Irish received winding up petitions from HM Revenue and Customs (HMRC) over an unpaid tax bill believed to be up to £1 million, which saw them forced out of business.

In October 2024, it was reported that Irish businessman and former Formula One motor racing team owner Eddie Jordan, alongside former New Zealand and South Africa internationals Andrew Mehrtens and Bobby Skinstad respectively, were forming a consortium to buy London Irish as part of a wider project to emulate the success of the City Football Group.

In February 2025, Strangford Ellis Ltd, led by Jordan, completed the takeover of London Irish, defeating German businessman Daniel Loitz in the bid. The consortium outlined plans to have the club playing rugby again by 2026, while remaining open to both a return to the Premiership and the possibility of joining the United Rugby Championship. In March 2025, the Jordan group announced further plans to establish a home ground in west London as well as a women's team and an academy setup before handing the club over to fan ownership.

Jordan died of cancer the following week. His son Kyle Jordan assumed the role of interim chief executive of the club and reaffirmed plans for a return to competitive rugby in 2026.
