DUP MP Jim Shannon is self-isolating at home after he had dinner at the same table as an SNP MP who tested positive for coronavirus.
The Strangford MP was seated at the same dining table as the SNP's Margaret Ferrier on Monday evening, his party said.
The room seating arrangements included proper social distancing measures, the statement added.
Ms Ferrier admitted she was tested for coronavirus on Saturday after developing symptoms but still took a train to London on Monday when she should have been self-isolating.
The SNP's Westminster leader, Ian Blackford, spoke to Ms Ferrier yesterday afternoon and announced that the party whip had been withdrawn.
On Wednesday evening, the Speaker's Office alerted Mr Shannon that he had been identified as a close contact of an individual who had tested positive for Covid-19.
The party statement added: "Upon receiving this news, Mr Shannon immediately self-isolated and on Thursday afternoon he received a negative Covid-19 test result.
"Mr Shannon sought and at all times has followed the advice of Public Health England and the House of Commons' Covid-19 team in dealing with every element of this incident.
"As a precaution, Mr Shannon is self-isolating at home."
