Three Suffolk MPs were not recorded as having voted on the report recommending suspending Boris Johnson from Parliament.
Ipswich MP Tom Hunt, Suffolk Coastal MP Therese Coffey and South Suffolk MP James Cartlidge were not included in an overnight list of MPs to vote on the report on Monday evening.
Matt Hancock, Dan Poulter, Peter Aldous and Jo Churchill all voted 'aye' to suspend Mr Johnson.
The result was announced in the chamber as 354 to seven, majority 347.
The initial division list released by the Commons authorities contained 352 names in the ayes and six for the noes.
It may be updated further by parliamentary officials to include any missing names to ensure the numbers match the ones announced in the chamber.
MPs endorsed sanctions against Mr Johnson recommended by the Privileges Committee, including banning him from having a pass to access Parliament, which is usually available to former MPs.
