Diageo has cancelled its sponsorship of London Irish Rugby Club over concerns at the signing of Paddy Jackson.
The drinks company said the signing of the former Ulster and Ireland out half was not consistent with their values.
27-year-old Jackson who was acquitted of rape last year signed for the club last month.
Diageo, which counts Guinness among its brands, is the second sponsor to withdraw from the club.
In a statement, the firm said: "We have met with the club to express our concerns.
"Their recent decision is not consistent with our values and so we have ended our sponsorship."
