Mahathir Mohammad, who took the road to progress to Malaysia, joined the opposition alliance in this year's national election and challenged Prime Minister Najib Razak. He says he wants to correct his mistake in the past.
Mahathir's association with Anwar Ibrahim's opposition came back to politics when he was dragged out of power after being accused of corruption against his once-time favorite candidate Razak.

Fourth National Election on May 9 in Malaysia The election was supposed to be one-sided because of Anwar's imprisonment, but Mahathir's return is now giving a sketch to the struggling battles.
Over the past six decades Najib's Barisan National (BN) coalition is in power in Malaysia. But in the past they never had to face tough challenges like this.
In a statement from a hospital in Kuala Lumpur on Monday, Anwar said, "I urge all of you to join the People's Movement to demand change."
Anwar, who was sentenced to five years in prison for homosexuality in 2015, has been in hospital for the past few months. She has undergone surgery on her shoulder. He is expected to be released before June 8, and his supporters are hopeful.
Earlier, in the Mahathir era, Anwar had to undergo six years of imprisonment for the same complaint.
In 1998, Mahathir fired Anwar from the post of deputy prime minister and sent him to jail.
Mahabir and Anwar decided to work together to forget the past hostileness in 2016, despite the allegations of corruption and money laundering against Najib.
Anwar said that his coalition with Mahathir has become the 'biggest concern' for the ruling party.
"Mahathi gave evidence of his strong attitude. He acknowledged the limitations of the past, apologized and sacrificed his time and energy to save the respect of our country and people. "
On the other hand, on Monday night, in an interview with a pro-government television television channel, Najib claimed that his victory was assured, "Our political foundation is still strong and refreshing. I'm very relaxed, because we have the ability to win (in the election). "
Najib is accused of smuggling millions of dollars from state funding. Which he has always denied.
