The Democratic Unionist party MP Ian Paisley could be forced to stand down and face a byelection after a serious breach of parliamentary rules.
The member for North Antrim is already facing a suspension from the House of Commons for 30 sitting days after becoming a “paid advocate” for the Sri Lankan government and failing to declare family holidays worth at least £50,000.
His suspension will have repercussions for Theresa May’s government. Her working majority will be reduced by one until November, as the government tries to pass contentious Brexit legislation.
The 30-day ban, if accepted, could trigger a recall petition following a recent change to legislation. If 10% of the electorate signs a petition within six weeks, a byelection would take place at which Paisley could stand again.
Political opponents in Northern Ireland, including the Ulster Unionist party, the SDLP and Sinn Féin, have called for him to resign or face a public vote.
A spokesperson for Sinn Féin said that in the absence of his resignation or being forced to stand down by the DUP “we will support a recall if the percentage of the electorate required to trigger a recall prevails”.
It could last 30 sitting days and is due to begin on 4 September, the committee said. Parliament is in recess over the party conference season, meaning the suspension would last well into the autumn.
