Golfer Shane Lowry has said his sponsorship deal with Irish construction firm Kingspan is now over.
The Cavan-based company was named in the Grenfell Tower inquiry final report, where it was accused of "dishonest strategies" in relation to its insulation.
A public inquiry into the devastating 2017 blaze that killed 72 people blamed the disaster on failings by the British government, construction industry and, most of all, the firms involved in fitting the exterior with flammable cladding.
The fire ripped through the 23-storey social housing block in one of London's richest areas during the early hours of June 14th, 2017. It was Britain's deadliest blaze in a residential building since the second World War.
Following the publication of the report, Kingspan acknowledged the "wholly unacceptable historical failings that occured in part of our UK insulation business."
The Offaly golfer has been sponsored by Kingspan since May 2017, one month before the disaster in which 72 people died.
In a statement, Lowry said both sides have "mutally agreed to discontinue our sponsorship relationship" which they believe is the "right decision for all concerned".
