Pakatan Harapan has been urged to state if Lim Guan Eng will be allowed to seek a third term as Penang chief minister, following the coalition's promise to set a two-term limit for the posts of prime minister, chief minister and menteri besar in its manifesto.

In a statement today, Gerakan Youth chief Tan Keng Liang said even though Harapan was not in power, a commitment towards enforcing the term limit on Lim would be a proof of its sincerity.

"I believe such promise can be easily fulfilled now without any further delay if Harapan is sincere in their pledge.

"If Harapan is unable to even keep this basic promise to limit the term of their own Penang chief minister to two terms, then it is very clear that the voters should not believe in any other electoral pledge in their upcoming election manifesto," said Tan.

By the next general election, Lim will would have served two full terms.

However, it is arguable that in those two terms, Lim was not technically part of the Pakatan Harapan coalition, which was formed in 2015.

Meanwhile, Tan warned voters that Harapan's predecessor, Pakatan Rakyat, did not fulfil many of its electoral pledges in the states it won.

This includes the pledge to implement local council elections, free tertiary education in Selangor, and to not raise utility rates, he said.

Penang's water tariff was increased in 2015, but only for those who use more than 20,000 litres of water a month.

In 2014, the Federal Court ruled that Penang was not exempted from Section 15 of the Local Government Act 1976, and therefore could not conduct local government elections.
