Despite promising to build a wall on the United States' border with Mexico "immediately" if he became president, Donald Trump has indicated he will scrap plans to find cash for his border wall in the spending bill.

However, he still insists that the wall - with an estimated price tag of £16.85 billion will be built by the end of his first term in office.

"The wall's gonna get built. It's going to have a huge impact on human trafficking," the President said, adding construction will start "soon".

He also took to Twitter to promise its construction.

The £780 billion ($1 trillion) spending bill must pass by Friday or could result in a government shutdown.

The bill funds federal agencies until the end of the year.

Democrats had promised to block the bill if money were earmarked in it for the wall which they, and many Republicans who's states contain large Hispanic populations, are against.

President Trump had proposed £1.2 billion for his wall as part of the spending bill.

However, stumbling blocks on the bill remain, with Democrats demanding money for insurance companies to help people on low-incomes afford health policies - also known as Obamacare - or that President Trump abandon a threat to use the payments as a bargaining chip.

Yet, Mr Trump's apparent willingness to back down on the wall issue may help to pass the bill.

Analysts say the president is under pressure to deliver on his election pledges, few of which have been fulfilled in his first 100 days in office.

Republicans are also going over proposed changes to their beleaguered health care bill and they hope to get enough votes for it to pass it through the House of Representatives.

On Monday, White House spokesperson Sean Spicer said that administration negotiators were "very confident" a shutdown would not occur.

President Trump said he would be willing to return to the funding issue of the wall in September.

House Minority Leader Nancy Pelosi, approved of President Trump's apparent shift: "The president's comments are welcome news given the bipartisan opposition to the wall, and the obstacle it has been to the continuing bipartisan negotiations in the appropriations committees."
