labour have been in power in the UK,2 months,and already the press are on their back day and night, why?

The long and the short of it is the fact that the UK has seen just about every form of conservatism over the 14 years they were in office.

And the only thing you can draw from it is that those who own newspapers; tv news outlets and several online sites means every reincarnation, whether it be Cameron and Osborne's 'Austerity' or Johnson's response to covid or Truss's high risk gamble with the economy that essentially bankrupted the current and next generation in order to back employers and businesses who haven't paid living wages sufficient for employees to pay their pensions to the point of retirement for a decade or more, meaning that most will either have to die working beyond the age of 70, or apply for scaled down benefits....will be supported by media owners UNTIL there are laws created that means THEY will have NO choice but to pay THEIR share.
Which they've skillfully avoided doing up to this current generation that don't watch or listen or read news anyway
