Tory chief Lee Anderson pledged to graft around the clock whilst on a sun-soaked jolly to the other side of the world.
The controversial MP has been enjoying a trip to Uruguay in South America with taxpayers left to foot the bill.
Mr Anderson was appointed by Rishi Sunak as deputy chairman of the Conservative Party in his reshuffle earlier this week.
But the top Tory has not started the job yet as he is on a trip to Montevideo, where temperatures have hit 34C (93.2f) this week.
In a video posted shortly after the announcement on Tuesday, Mr Anderson said he was "incredibly proud" to have been promoted by the PM.
"I'm going to take this new role really, really seriously, grafting seven days a week, 12 hours a day for the next 18 months up until the next general election," he added.
Rather than getting to work immediately, the clip showed Mr Anderson was in his hotel room abroad dressed down in a black T-shirt.
In another post on Wednesday, Mr Anderson urged people to join the Conservative party whilst standing in front of some palm trees wearing a white polo shirt.
It is understood the visit to Uruguay by some MPs on the home affairs select committee is being paid for by Parliament.
The Prime Minister today distanced himself from the Ashfield MP after he backed the return of the death penalty.
Mr Sunak said "that's not my view, that's not the Government's view" when questioned about reinstating capital punishment.
In an interview with The Spectator magazine earlier this week, Mr Anderson said he would support the UK reintroducing the death penalty.
He said: "Nobody has ever committed a crime after being executed. You know that, don't you? 100% success rate."
He also suggested using Royal Navy frigates to return to France those arriving in small boats across the English Channel.
"I'd put them on a Royal Navy frigate or whatever and sail it to Calais, have a stand-off. And they'd just stop coming," he said.
Mr Anderson has been no stranger to controversy since being elected to Westminster in 2019, having criticised food bank users and the England men's football team for taking the knee in protest at racism.
In an interview yesterday with BBC Radio Nottingham, Mr Anderson became defensive when challenged about being caught asking a friend to pose as an anti-Labour swing voter on the doorstep during the 2019 election campaign.
Mr Anderson refused to reply when asked if he was dishonest. Instead, he asked the reporter 10 times if she had ever lied.
When she said that she had, Mr Anderson said: "So you're dishonest."
Mr Anderson did not respond to a request for comment on his trip to Uruguay.
