Datuk Seri Najib Razak cut short his holiday, and returned last Saturday to tour badly hit flood areas to monitor relief efforts as well as meet evacuees, who numbered close to quarter of a million earlier this week.

But the conspicuous absence of his wife by his side triggered questions from online users.

"@NajibRazak Rosmah kat mana (where is Rosmah), Rosmah Rosmah kat mana (yeaa), Rosmah kat mana, Rosmah Rosmah kat mana (ditanya tanya lagi) (asking again) #TaufikBatisah," tweeted Lucius Maximus, mocking a short video clip which had gone viral not long ago.

Kedahkini also asked: "ROSMAH MANSUR KAT MANA?".....TERUS JADI TANDA TANYA (where is Rosmah Mansur?...remain a question)"

MMXII (@faarahs_) tweeted in Malay: "@_puteriazman rosmah ada tak? Hahaha ada petanda tu (was Rosmah around? Hahahah, it's a sign)."

In a tweet tagging several others, including Najib and Gerakan Youth chief Tan Keng Liang, Philbert Lorickson wrote: "mana rosmah? (where is Rosmah?) Why no go kelantan? (Why has she not gone to Kelantan?) Ahliang can you ask this question (?) please repeat 100x (100 times)?"

Megat Trainor (@akeemzamani) posted sarcastically: "Rosmah ulang alik kt US shopping barang utk mangsa banjir kot #Husnuzon" (Rosmah may be travelling back and forth to the US to shop for things for flood victims), and got a cheeky reply from Munifah (@mo0n94): "alhamdulillah (praise be to God). Mcm ni la FLOM yg kita nak (This is the first lady of Malaysia that we want)."

Datuk Seri Najib Razak's Twitter account was filled with pictures of him speaking to flood evacuees. – Mohd Najib Tun Razak Twitter pic, January 1, 2015.Rosmah's absence from the country at a time of national disaster has led to allegations she was not practising what she preached.

In a November 7 report in The Star, Rosmah was quoted saying that the wives of the country’s leaders and people’s representatives played a pivotal role in motivating them to serve the rakyat better.

“Behind every successful husband is a loyal and supporting wife. As wives of politicians, it is our duty to support and motivate our husbands and ensure they can better serve the rakyat,” she had said.

In the report, Rosmah, who is president of the Association of Wives of Ministers and Deputy Ministers (Bakti), said women should improve their soft and inter-personal skills, in educating the public on current political issues.

C.H.U.R.A (@chura_s) also lashed out at those questioning Rosmah's whereabouts, saying in a tweet: "Rosmah Mansur tak balik Mlsia dgn Najib pun nak jd issue. (Why make a fuss over Rosmah Mansur not returning to Malaysia with Najib). Get a life, people! Its 2015! Stop complaining!"

Questions have also been raised over the official government jet to carry the prime minister.

Najib and his family had taken the jet to go on holiday but he returned on a Malaysian air force aircraft.

PKR had questioned the government about the missing jet, asking if it was true the plane was in Indianapolis in the American Midwest, and demanded to know who it was beng used for following Najib's return home.

Pressure is mounting on the government to explain the whereabouts of the plane, with many demanding to know whether public funds were being misused. – January 1, 2015.
