I cannot think of one relating to foreign interference, except for the matter of sanctions against U.K. members of Parliament who had criticized China. In that case, it wasn't dealt with as contempt. It was a state-level action, and the response was to make it clear that the Chinese ambassador was no longer welcome, although other members of the embassy are permitted to enter the precinct.
That's the state level. It was not treated as contempt. It's hard to see how it could have been, because it depends on someone being in the jurisdiction, and there is a particular sensitivity about diplomatic staff.
In principle, the House of Commons' powers to take action against them are unlimited. In practice, they are at liberty to leave the jurisdiction, and in exercising those powers, you would invite members to think very carefully about the framework of the Vienna convention, which is supranational law, and about the possible implication for U.K. diplomats abroad.
As I say, that sanctioning of U.K. members of Parliament for what they had said in Parliament was not taken through the contempt jurisdiction.
In terms of intimidation, which was dealt with as contempt, the most recent attempt was somebody saying they would take legal action against a member for what they had said, if they repeated what they had said in the House. Other similar contempts were saying that you would withdraw funding for activities in a member's constituency, or that you would affect selection.
Not much of our case law goes to foreign intimidation.
