Jaitley described the move by AAP ministers and MLAs shunning beacon fitted official cars and VIP culture as "showmanship".
"Our Goa chief minister goes to office on his two-wheeler but the national media is in Delhi and not in Goa..
"I have gone to Mamata Banerjee's home..Probably no politician lives a more austere life than her. There are many such people in national politics.
" I have been in Parliament for the last 14 years but never stayed for a day in a government bungalow. We don't show off doing such things by displaying them on our arms. Had he been austere, why did he (Kejrwal) take two houses of 5-5 bedrooms each."
On Kejriwal government announcing 20,000 litres of free water every month and hiking up subsidies to halve power bills in Delhi, Jaitley said, "the states which provided cheap power to farmers have found that such sops alone are not enough to win elections.
"Today, there are 30 per cent localities in Delhi which are unauthorised and do not have laid pipelines. Most of the people who live in slums do not have tap water.
"The first priority should have been to increase the network and supply water to all for a reasonable time. All this (free sop) is out of the purview of this system.
"There are water connections which are unmetered, which is against the system. There are defective meters, which are also against the system.
" Only those having metered connections and limiting their consumption will benefit. Co-operative housing societies are out of this domain. You can give subsidies which every government gives, but the benefit of subsidies should reach the weaker sections."
