Sir Keir Starmer has paid back more than £6,000 worth of gifts and hospitality after a row over his acceptance of freebies.
The Prime Minister and other cabinet ministers have faced weeks of backlash for accepting free donations from wealthy donors since entering No 10 in July.
Mr Starmer is now covering the costs of six Taylor Swift tickets, four tickets to the races and a high-end clothing rental agreement for his wife.
Speaking in Brussels on Wednesday, the prime minister said his government would bring forward new principles for donations "as until now politicians have used their best individual judgement to decide".
"I took the decision that until those principles were in place it was right to repay these particular payments,” he said.
A Downing Street spokesperson confirmed the the ministerial code would be updated and will include “a new set of principles on gifts and hospitality” commissioned by Sir Keir.
"Ahead of the publication of the new code, the prime minister has paid for several entries on his own register.
"This will appear in the next register of members' interests."
The gifts Mr Starmer has paid four include Taylor Swift tickets from Universal Music Group worth £2,800, two from the Football Association at a cost of £598, and four to Doncaster Races from Arena Racing Corporation at £1,939.
A clothing rental agreement work almost £900 for his wife along with one hour of hair and makeup was also covered by the prime minister.
