Donald Trump’s approval rating has slipped to an all-time new low of 35 per cent, according to the latest polling data.

The Gallup poll, which is based on approximately 1,500 calls to adults in America each day, notches the US President one percentage point lower than his 36 per cent polling yesterday.

More than 20 governors and mayors from across Oregon, Washington and California have already said they will fight Mr Trump's attempt to dismantle Mr Obama's Clean Power Plan.

The 70-year-old billionaire’s ‘disapproval’ rating is also at its highest rate since his inauguration, ranking at 59 per cent.

It represents an almighty slip from when, two days after he was made leader of the free world, Mr Trump had a fairly respectable 45 per cent approval rating.

It dipped over the next month but returned to 45 per cent on 11 March as Republicans prepared the replacement of ‘Obamacare’.

A Qunnipiac University poll last week found a 37 per cent approval rating for Mr Trump’s “handling of his job”.

That was also an all-time low for Quinnipiac, which recorded a 56 per cent disapproval rating, after a week-long survey of 1,056 voters.

Mr Trump has previously teased Barack Obama for his ratings, which at their lowest, slipped to 38 per cent in both 2011 and 2014.

“@BarackObama has a record low 39% Gallup approval rating. Why so high?” wrote Mr Trump, on Twitter, in August 2011.

In October 2008 Republican George W Bush reached his lowest rating of 25 per cent in the wake of the global financial crisis.
