Boris Johnson always sucks up a lot of oxygen.
But at this week's Conservative Party conference in Manchester, he's starved his colleagues of almost any puff of clear air at all.
The UK Foreign Secretary's latest headline-grabbing intervention was a flippant remark about Sirte — a Libyan city that was, until recently, a stronghold of the Islamic State terrorist group.
Mr Johnson told party members British investors have a "brilliant vision" to "turn it into the next Dubai".
"The only thing they've got to do is clear the dead bodies away and then we will be there," he said.
Of course, the fairly undiplomatic comment from Britain's top diplomat is not out of character.
During his tenure he's also compared the goals of the European Union to those of Napoleon and Hitler and accused UK ally Saudi Arabia of engaging in "proxy wars" in the Middle East.
But it's not his relatively regular gaffes that are most concerning colleagues, rather his "back-seat driving" of Brexit.
He strayed well beyond his ministerial brief last month, by outlining his personal "vision for a bold, thriving Britain" in the Telegraph newspaper.
Then, on the eve of this current conference, Mr Johnson spoke to The Sun about what he wouldn't accept when it came to negotiations with the EU.
The freelance policy making seems an attempt to undermine Prime Minister Theresa May, who lost much of her authority along with her parliamentary majority at June's early election.
The odd Tory backbencher and Manfred Weber — a key ally of German Chancellor Angela Merkel — have suggested he should be sacked.
But that seems unlikely, mainly because it might just do Ms May more harm than good.
From the backbenches, Mr Johnson would have the freedom to write, tweet and make colourful observations to his heart's content.
A Tory leadership election is considered probable in 2019, after Brexit negotiations are finished, and according to one poll his recent comments have once again helped him become the favourite among grassroots members.
But Mr Johnson's current role of Foreign Secretary has responsibilities and restrictions.
His perceived disloyalty to cabinet colleagues and occasional undiplomatic comments continue to upset and annoy.
The position may ultimately provide him with enough rope to ruin his own chances of ever taking the top job.
At least, that seems to be the hope of Ms May and her closest allies.
