Joe then renewed his own training licence for some years before retiring. Aidan O’Brien was champion Irish National Hunt trainer in the 1993/4 season and went on to lift the title for the next 5 consecutive seasons.

as stable jockey. Kinane was replaced by the young Jamie Spencer who had developed a good reputation riding in the UK. However the year ultimately proved disappointing on the track. Spencer was replaced after a string of self-confessed mistakes on Powerscourt in the Arlington Million and on the same horse again in the Breeders' Cup Turf. *2005 season Kieren Fallon replaced Spencer as Ballydoyle's stable jockey. On the first classic weekend of the 2005 flat season the newly formed partnership of Aidan O'Brien and Kieren Fallon took home both the 2,000 Guineas ( Footstepsinthesand) and the

on Arc day at Longchamp. In one of the races of the season he was beaten by a head in the Dewhurst Stakes by European Champion 2-year-old Teofilo. Much anticipation centred on the expected rematch of these two colts in the 2,000 Guineas at Newmarket the following spring. Aidan finished the season with prizemoney of over €6.5m in Ireland and Great Britain. The season was marked however by the emerging race fixing allegations involving stable jockey Kieren Fallon. On 3 July 2006, Fallon was charged along with 7 other people for conspiring to defraud clients of the internet betting exchange Betfair. Fallon was one of 28 people answering bail at Bishopsgate police station in the City of London in connection with the inquiry. In a released police statement, he was described as being charged with "offences relating to allegations of fixing the outcome of horse races between 1 December 2002 and 2 September 2004, and money laundering". He was among three jockeys charged, along with Darren Williams and Fergal Lynch, all of whom had their licences to ride in Britain suspended, effectively under the principle that they would be guilty until found innocent. Fallon's problems were further compounded when on 29 November 2006 the French racing authority France Galop suspended Fallon for six months after he tested positive for a metabolite of a banned substance. *2007 season The end of the 2006 season had apparently left Ballydoyle with multiple options for the following year's classics. However the opening part of the season was left in turmoil after the premature retirement of Holy Roman Emperor. The previous year's champion miler George Washington proved almost infertile, ultimately siring only one foal. As a late replacement, Holy Roman Emperor was sent to Coolmore Stud. Plans had to be drastically changed with O'Brien saying "all our eggs were in one basket" in relation to the opening classic of the season the

As a team Aidan and Johnny were to dominate the Irish classic scene taking all five Irish Classic Races thus being the first trainer to do so since 1935. He again was named Champion trainer in Britain taking his second title in a row. He equalled former Ballydoyle resident Vincent O'Brien's record of 6 winners at Royal Ascot, four of these at the highest level including Yeats' record-equalling third consecutive
