Langley, 34, was drunk and in the Band in Wall music venue in Manchester in the early hours of October 1 when he touched the two women, Manchester Magistrates’ Court was told.
The actor, who left the ITV soap in the wake of the allegations after playing Todd Grimshaw for more than a decade stood in the dock today and pleaded guilty.
The court heard he also ‘sexually touched’ two other women on the same night, but was not charged with those offences, said prosecutor Karen Saffman.
Langley, whose family members wiped back tears after his guilty pleas were entered, was told he could face a possible jail sentence.
But district judge Mark Hadfield asked for a probation report to be prepared on Tuesday before he decides whether he will sentence Langley or whether the case needs to be sent to Manchester Crown Court where the defendant could face a longer sentence.
Following his arrest, Langley announced he had quit his role in the ITV soap, and thanked the cast and crew for working with him over the past 17 years.
He said: “Sadly, I will no longer be working on Coronation Street.
“Acting on the show has been the fulfilment of a personal dream. Playing the role of Todd Grimshaw since I was 17 years old has been a huge part of my life, and an absolute honour.
