Malaysian politicians are prone to using bizarre analogies, and Senator Mohd Ali Rustam is no exception.

The former Malacca chief minister likened the much opposed Goods and Services Tax (GST) to a forced marriage.

Though viewed as something negative, he told the Dewan Negara, the new tax would yield positive results in the long run similar to the 160 countries that have enforced GST.

"It is like telling our child to get married, but our child does not like to do so. So after the marriage, perhaps for the first, second and third night, the couple may sleep separately.

"But as time goes on, it seems fine, then at the end of the year, they have a baby, not one but up to four kids.

"I feel GST is like a forced marriage, it would look bad but is actually good because it has been tested in numerous countries," he was quoted as saying by the BN Backbenchers Club portal.

Mohd Ali raised this issue when debating on the Yang di-Pertuan Agong's royal address.

However, the senator said enforcement must be enhanced with regard to the GST to show that it is better than the Sales and Services Tax (SST).

He argued that the government's efforts were in line with the six main pre-conditions which is to ensure the future of the nation, peace, vibrant economy, ample employment opportunities, increasing income levels, low poverty rate as well as low and moderate inflation rate.

"In this aspect, Prime Minister (Najib Abdul Razak), who is also finance minister, must be praised for his sterling success in preserving peace and harmony as well as steering the nation's economy," he added.

Mohd Ali also lauded the prime minister for having reduced the crime rate.
