However, Melanie is upset by Lisa's accusation and Phil comforts her, leading to a one-night stand.
Melanie, however, realises it was a mistake and reconciles with Steve Owen (Martin Kemp), making Phil jealous.
Phil is one of the major introductions made by executive producer Michael Ferguson, who wanted to bring in some macho, male leads.
Phil and his brother Grant became popularly known as the Mitchell brothers in the British media with Phil initially portrayed as the more level-headed of the two thugs.
Storylines featuring the Mitchell family dominated the soap opera throughout the 1990s, with Phil becoming a popular and long-running male protagonist into the 2000s and the 2010s.
Mc Fadden temporarily left the series in late 2003 then returned in March 2005 for a short stint, before making a permanent return in October 2005.
He later follows Kathy to the airport but is stopped by Kathy's son, Ian Beale (Adam Woodyatt), who persuades him that Kathy and Ben are better off without him. He starts seeing Lisa Shaw (Lucy Benjamin), but the relationship stalls when Kathy returns briefly in 1999 and sleeps with Grant.
