California governor Gavin Newsom has issued executive order for removal of homeless encampments in his state.

Mr Newsom’s order would direct state agencies on how to remove the thousands of tents and makeshift shelters across the state that line major roads, clutter shopping centre car parks and fill city parks.

The order makes clear that the decision to remove the encampments remains in the hands of local authorities.

The guidance comes after a decision by the US Supreme Court earlier this summer allowing cities to enforce bans on sleeping outside in public spaces.

The case was the most significant on the issue to come before the high court in decades and comes as cities across the country have wrestled with the politically complicated issue of how to deal with a rising number of people without a permanent place to live and public frustration over related health and safety issues.

“We must act with urgency to address dangerous encampments,” Mr Newsom said in a statement.

While Mr Newsom cannot order local authorities to act, his administration can apply pressure by withholding money for counties and cities.

Mr Newsom has made homelessness a signature issue as California governor.

He pushed and campaigned for a ballot measure earlier this year to allow the state to borrow nearly 6.4 billion dollars to build 4,350 housing units.

The order comes as Republicans have stepped up their criticisms of California and its homelessness crisis as vice president Kamala Harris — a former California district attorney, attorney general and senator — launches her presidential campaign.

Ms Harris entered the race over the weekend after President Joe Biden announced that he would not seek re-election.
