DUP MPs did not vote on a damning report that found Boris Johnson lied to Parliament over Covid lockdown parties at Downing Street.
No vote was recorded for all eight of the party's MPs when the Commons on Monday night overwhelmingly backed the Privileges Committee's findings by 354 votes to seven.
SDLP leader Colum Eastwood and Alliance deputy leader Stephen Farry voted in support of the report, which found Mr Johnson deliberately misled MPs with his partygate denials.
