Ukraine Conflict: Did the UK sanction 100 people last week?

At Prime Minister's Questions, Boris Johnson told MPs the actions the UK had taken in response to the invasion of Ukraine "are having an effect in Moscow".

He said the UK had sanctioned "275 individuals already, a further 100 last week, the impact is being felt".

Mr Johnson has referred to the 100 figure several times in the past week. But when Reality Check asked for the names of the 100, the government could not provide them and said: "We'll let you know as soon as we have further details to add."

Instead, it sent a list of every person and company currently sanctioned by the UK, including people from Iran and North Korea. It shows that 15 individuals have been sanctioned in the past week:

When asked about this, the prime minister's spokesman said there were 100 individuals and entities.

While the prime minister specified individuals, also adding companies doubles the number, but still does not get to 100.

But UK officials told BBC News that the figure also includes the major subsidiaries of the companies. They said, for example, the sanctioned company Rostec has about 60 subsidiaries, all of which could count towards the number sanctioned.

We also asked about the 275 figure Mr Johnson mentioned but the government did not provide the details.

Of all the people on the list (not just those sanctioned in the last week), we counted 195 who had been sanctioned as a result of measures linked to Russia.

But these date back to the Salisbury poisonings, when a former Russian spy and his daughter were targeted by Russian agents.

On Wednesday, Mr Johnson said the government would publish a list of all those with assets related to the Kremlin but failed to say when.

Sanctions he has announced so far include:
