"The by-election was a referendum on him. Their entire line of campaigning was that this new leader must be given a chance.
"They said that Umno made a mistake in the past and now it should be given a chance under Najib...that's fine.
"And they even brought back Dr Mahathir...that was the problem," said Anwar in a press conference at the PKR headquarters this morning.
The Opposition Leader added that the Umno/BN campaign was to promote Najib's unity call involving all races, apart from playing up the Malay supremacy race card.
"But that has crumbled," he said.
Anwar said that Najib should now have some humility to acknowledge that his calls for reforms have failed.
"He must take the initiative to make the reforms," he added.
He also dismissed suggestions that Najib would be calling for a snap election anytime soon.
"Umno will not consider that at all. If they do, god willing, we will form the next government," he said.
He added that unlike Umno, PKR and Pakatan would not play the race cards to win elections.
He said that in their campaigns in the by-elections, they had stressed that they will look everyone as the same.
"We must appeal to Malays to endorse all candidates, even non-Malays and non-Muslims. This shows our maturity," he said.
And it was this which he said resulted in the Chinese and the Indians continuing to support Pakatan candidates in both Bukit Gantang and Bukit Selambau.
He also added that the Malay support in Bukit Gantang was sustained while it was increased in Bukit Selambau.
Fairus to remain state rep
Anwar also suggested that his candidate in Batang Ai Jawah Gerang could have lost the by-election as a result of some vote-manipulation.
"We did not make a mistake in naming him. I think he was the right candidate.
"He lost in the interior areas, areas where the votes were not counted in places where they should be counted," he said.
He also joked by saying that PKR would have won in Batang Ai if Umno had sent its former premier Dr Mahathir Mohamad over there for campaigning.
He refused to comment further on Mahathir's last-minute campaigning for Umno in Bukit Gantang and Bukit Selambau.
"No comment on Tun. Let him say what he wants to say about me... he has been doing that for a long time."
Anwar also rubbished speculations that Penang Deputy Chief Minister (1) Mohammad Fairus Khairuddin will be resigning as the Penanti state representative.
"Not true. He will resign as the deputy chief minister and state exco member effective today. Nothing else," he said.
When pressed by journalists if the Penanti seat will become vacant soon, Anwar said Fairus will be the state representative for the seat until the next general election.
Anwar was also asked on the ‘big announcement' which he was supposed to make after the by-elections.
He was originally slotted to be making the announcement during a ceremah at Bukit Selambau but he held back stating that the time was not right.
Today when asked about it, Anwar said that he had actually made a big announcement in Bukit Selambau in regards to the defections of PPP members into PKR.
"We announced the virtual dissolution of Kedah PPP. Isn't that a major announcement?" he asked.
