has been warned that his extensive looks like he is "fleeing" as support for in the polls crumbles.

The Prime Minister's personal approval rating has also slumped since he took on the role following a in July.

polling for The Times in mid-December found that Sir Keir's net favourability rating had fallen to its lowest ever level again, at -41.

Two thirds of Britons said they had a negative view of the prime minister (66%), compared to only a quarter with a positive view (25%).

Pollsters added that is also more unpopular than it has ever been.

Between December 21 and 23, more than six in ten Britons (62%) said that they disapproved of the government's record to date, while only 17% approved.

Even Labour voters, YouGov reportes are now divided on the government they elected, with 38% having a negative view and 34% a positive one.

Now, reports that Sir Keir travelled abroad on official business more in his first six months in power than any of his immediate predecessors.

He has spent 31 days on working trips since he took office, which, discounting the seven-week prime minister Liz Truss, is significantly more than the 19-day-average for all his predecessors going back to Tony Blair in 1997.

As of December 10, in 15 trips, the Prime Minister has visited 13 different countries, including France, the US and Germany three times each, reports.

Victoria Honeyman, professor of British politics at the University of Leeds, said: "Being an international prime minister can be incredibly positive."

She added: "If the domestic situation doesn't turn, if it doesn't start to pick up, then the criticisms of him being essentially absent will get an awful lot of traction because it looks like he's even essentially fleeing."

YouGov added that almost half of Labour voters (46%) said in mid-December that they had expected Labour to do well but have been disappointed.

Just 28% consider the party to be doing well - a figure which falls to 10% among the wider public.
