Rahul Gandhi on Tuesday asked voters in Punjab not to look at the face of leaders but their actions to understand the "hidden powers" that are at work behind them, as the former Congress president attacked Prime Minister Narendra Modi and AAP leader Arvind Kejriwal.

Taking on the Aam Aadmi Party (AAP), he claimed those seeking one chance to form the government will "destroy Punjab" and the state "will burn".

Gandhi also targeted former chief minister Amarinder Singh who the Congress leader said was removed by the party last year for hobnobbing with the BJP.

Addressing a poll rally at Rajpura, about 30 km from here, for the February 20 Punjab assembly polls, Gandhi again cautioned people against going for any "experiment" in Punjab polls, saying only his party was capable of maintaining peace in the border state.

"The most important thing for Punjab is its peace. This is not a laboratory, not a chemistry lab or any such place where experiments can be done. Punjab is a border and sensitive state and only the Congress party understands Punjab and can maintain peace in the state," he said.

"Those who are making promises to you, saying 'ek baar mauka do', they will destroy Punjab. Punjab will burn, remember my words," he said attacking AAP. Gandhi said he has been in politics since 2004 and, if any new person comes, that individual says "look he is Modi, Kejriwal, Gandhi, and that new person only sees a face".

"But one who has some experience says there is a face but which force or power is behind it. I am standing here, you ask the question which power is behind him," he said.

"Modi is standing, don't look at his face, but you ask which all hidden powers are behind him and then look at their actions, then you will understand politics," he said.

The Congress leader criticised Modi for demonetisation and the farm laws.

"Is the power of the poor is behind Modi. No, the poor are suffering. Modi then brought three black bills for destroying the lives of farmers. He is not a single person, there are hidden forces behind him.

"Farmers were protesting for a year and there cannot be the power of farmers backing him. Otherwise, 700 farmers would not have died," he said.

He then told the gathering "look which force is behind Modi".

"Who was trying to snatch what the farmers have? The country's biggest three-four billionaires wanted to snatch. They say there is a lot of money with farmers, fields and government warehouses and we want it," said Gandhi.

He then also attacked the AAP leader and Delhi Chief Minister Kejriwal. "Then Kejriwal comes, think which forces are hidden behind him, when you understand this and by closing your eyes which force was behind Kejriwal, you will understand Punjab politics," he said.

Again targeting Modi, Gandhi said, "In India, petrol and diesel prices are constantly on the rise, which power is getting the benefit?''

After a reply from the gathering, Gandhi then said, "These are the same powers which got farm laws implemented, did demonetisation, GST.. Modi is not an individual, behind him there is power".

He then said Modi did not lower petrol and diesel prices, but Punjab Chief Minister Charanjit Singh Channi did.

"Had there been the same power behind Channi, he would never have been able to lower these prices. But your power is behind our the chief minister and he did it. This is the fight," said Gandhi.

Priyanka Gandhi calls 'BJP & AAP two sides of same coin'

Congress leader Priyanka Gandhi Vadra on Tuesday campaigned for party candidates in Punjab and said like the BJP earlier propagated Gujarat model', AAP supremo Arvind Kejriwal was publicising his Delhi model', which she said was also a failure .

Riding a tractor with Punjab Chief Minister Charanjit Singh Channi in Rupnagar district as part of her Jansampark Abhiyan', Gandhi, who later addressed a gathering, also dubbed the BJP and AAP "two sides of the same coin".

She added that both AAP and BJP are promising a new brand of politics to befool the public.

Claiming that the Aam Aadmi Party (AAP) "emerged" from the Rashtriya Swayamsevak Sangh (RSS), she said it has an ideology similar to that of the BJP.

The Congress leader also accused the AAP, the main opposition party in Punjab, of doing nothing in Delhi and said its government has been a "failure".

People must be wary of the Delhi model of governance being touted by the AAP as even the BJP came to power at the Centre showcasing its Gujarat model in 2014, but the reality is now before everyone, she said.

People have seen the reality of the Gujarat model and now AAP is showcasing the Delhi model, she said.

" In Delhi, there is nothing in the name of improvement in health and educational institutions or employment. Understand these things," she told the audience.

In an apparent dig at Kejriwal and Prime Minister Narendra Modi, the Congress general secretary said, "Make them understand that one does not become a Sardar by wearing a 'banwati pagri' (turban) on stage (during campaigning).

"Make them understand who the real Sardars are... make them understand that Punjab is Punjabis," she said.

"Form your own government here. AAP will not give you any new politics nor Narendra Modi. Over here, new politics is here," she said, pointing to Channi.

Hailing the Congress-led government in the state, Gandhi said Channi took many courageous decisions during his short stint of 111 days "for the people of Punjab".

"Those who come from outside and talk to you about Punjabiyat, teach them what Punjabiyat means," she said.

Seeking to strike a chord with the locals, Gandhi also mentioned that she was married into a Punjabi family.

Punjab goes to polls on February 20.
