Boris Johnson had to ask German leader Angela Merkel to put herself on mute after she interrupted his remarks to a virtual meeting of G7 leaders.
The Prime Minister's address from 10 Downing Street did not get off to a smooth start - as with many lockdown video conferences.
While French president Emmanuel Macron was around 15 seconds late, the German chancellor appeared to forget to put herself on mute and could be heard in the background of the Prime Minister's opening remarks.
Mr Johnson asked: "Can you hear us, Angela?," before adding: "I think you need to mute."
He kicked off the meeting by waving at those on screen, saying it was "great to see all of you" before beginning the discussion.

Later in his remarks, Mr Johnson urged the G7 leaders to work together on "building back better" from the pandemic - using this to make a quip about US president Joe Biden.
He said it was a slogan that Mr Biden has used, adding: "I think he may have nicked it from us but I certainly nicked it from somewhere else - probably some UN disaster relief programme."
Mr Biden could be seen laughing on the video call on the screen inside the Cabinet Room.
The Prime Minister expressed his hope during the meeting that the G7 leaders would be able to meet "face to face" for the summit in Cornwall in June.
And the group also discussed a wide range of issues, including the worldwide distribution of coronavirus vaccines and preventing future pandemics.
Mr Johnson previously became the first world leader outside North America to speak to Biden earlier this month.
The Prime Minister was photographed in good spirits while speaking to his counterpart across the Atlantic on January 23.
The pair were said to have bonded over trains and past slogans on the 40-minute call - like their interaction on the G7 video conversation.
