Republican Nikki Haley enters 2024 presidential race

Nikki Haley, a former South Carolina Governor and United Nations Ambassador, has announced she is a candidate to become US President in 2024.

"Now is not the time to hold back. Now is the time for a strong and proud America," she tweeted, linking to a campaign video.

She is the second major Republican candidate to run, after ex-boss Donald Trump launched his bid in November.

Ms Haley is the third Indian American to seek a presidential nomination.

She said in 2021 she wouldn't challenge him for the White House, but changed her mind in recent months, citing the need for "generational change".

Other Republicans expected to launch a campaign to be selected for their party include Florida Governor Ron DeSantis and former Vice-President Mike Pence.

She has previously criticised Mr Trump's behaviour up to and during the January 6, 2021 attack on the US Capitol by his supporters.

The day after the riot, she said in a speech that "his actions since election day will be judged harshly by history".

Nikki Haley was previously a UN Ambassador in the Donald Trump administration

Most early polls show Mr Trump with a comfortable lead in South Carolina, whose primary he won on his way to the Presidency in 2016 - an indication of the uphill battle the former ambassador will have, even on what should be friendly ground.

A recent survey by the polling firm Trafalgar Group that included current and likely candidates has Mr Trump in first place with 43 per cent and Ms Haley in fourth at 12 per cent.
