Sungai Besar Umno division chief Jamal Md Yunos could lead the country in the future if the Pakatan Harapan government regresses and fails to push for changes in all aspects evenly.

This was the warning issued by the outgoing PKR Youth chief Nik Nazmi Nik Ahmad at the wing's congress in Shah Alam today.

"If we are too careful or shy, then the renewal - be it economic, administrative, political or social - will not happen. Malaysia will be dead and not go anywhere," he said.

"A good government needs to make an effort to push for changes evenly," he said in his policy speech.

"Sociopolitical progress must be strengthened by a fair and continuous economy," he added.

He then warned of how Donald Trump had succeeded Barack Obama as US president, while the UK had voted to withdraw from the European Union.

"Don't we forget, eight years after the Americans voted the first African-American as president, (they elected) an individual name Donald Trump.

"In UK, after the era of openness and moderate brought by Tony Blair, Gordon Brown and David Cameron, it was followed by Brexit," he added.?

"We don't want 'Jamal Jamban' to become the (country's) leader, but nothing is impossible if we are not careful," he said.

He also likened the PKR election to the 2016 US presidential election, which pitted Democratic nominee Hillary Clinton against Republican candidate and eventual winner Trump.

"Our election is colourful, but this is normal in any democratic political party. What is important is that when this is over, we should close ranks.

"Malaysians and the world are not interested in what happened in our?kelambu

?(mosquito net), they want us to show a high level of performance," he said.

The rakyat today no longer fear for a change in the government, he said.

The Setiawangsa MP insisted that Harapan must fulfil its election promises as the political coalition is answerable to the party and God.

"Race and religion cannot be an excuse," he said, adding that those who played up the sentiments of the rakyat only want to serve their own personal interest.

He said the majority of the people supported the agenda of change.

"What we need is a radical change in our mindset, politics and administration," he said.

Meanwhile, he appealed for fugitive businessperson Jho Low to return and to subject himself to trial in Malaysian court.

"We urge Jho Low, if he's watching a live stream of PKR Youth wherever, come back. Surrender himself and defend himself in Malaysia's legal system," he said.?

Two weeks ago, Low was charged in absentia with conspiring to launder billions of dollars from 1MDB and violating the US Foreign Corrupt Practices Act (FCPA).

Following the charges, Low has maintained his innocence, saying he has held no formal positions at the beleaguered 1MDB, nor ever employed by the Malaysian government, among others.
