Nusli Wadia, an independent director of some companies of the Tata Group slapped a defamation notice on Tata Sons board asking to withdraw the allegations against him as they are "false, defamatory and libelous with the intention of harming (his) reputation".

Wadia has asked the board to present evidence against the allegations that he acted "in concert" with Cyrus Mistry, the former Tata group chairman.

"Please furnish details of all events and occurences that prove I have acted in concert," says the eight-page letter Wadia wrote to the 10 board members of Tata Group, including Cyrus Mistry.

He has also asked the board to define "Tata Group" stating that as an "independent director of Tata Steel am I under an obligation to act in the interest of an undefined Tata group."

"In any event, I must remind you that as an independent director, my only fiduciary duty is towards Tata Steel Limited and not an undefined Tata group or Tata companies," Wadia said in his letter.

Democrat Tulsi Gabbard, the first Hindu lawmaker in the US Congress, today met president-elect Donald Trump amidst speculation that she is being considered to be made the American Ambassador to the United Nations.

Gabbard, 35, who was re-elected for her third consecutive term on November 8, was among the first politicians to meet Trump in New York. She has been a vocal critic of President Barack Obama on confronting the radical Islamic terrorism.

"President-elect Trump asked me to meet with him about our current policies regarding Syria, our fight against terrorist groups like al-Qaeda and ISIS, as well as other foreign policy challenges we face," she said hours after meeting Trump here.

Amidst speculation that she is being considered for the position of US ambassador to the UN, Gabbard - a Democrat - defended the meeting as in favour of national interest.

US President-elect Donald Trump has vowed to pull out of the Trans-Pacific Partnership (TPP) on his first day in office, calling it "a potential disaster for the country."

Trump in his first video-message yesterday, after being elected as the President of the US, outlined concrete steps that he will take to "Drain the Swamp" in Washington DC and put America First by focusing on the issues of trade, energy, regulation, national security, immigration and ethics reform.

My agenda will be based on a simple core principle: putting America First. Whether its producing steel, building cars, or curing disease, I want the next generation of production and innovation to happen right here, in our great homeland: America ? creating wealth and jobs for American workers," Trump said.

"As part of this plan, Ive asked my transition team to develop a list of executive actions we can take on day one to restore our laws and bring back our jobs. Its about time," he said listing out some of the key steps that he would take.

"On trade, I am going to issue our notification of intent to withdraw from the Trans-Pacific Partnership, a potential disaster for our country. Instead, we will negotiate fair, bilateral trade deals that bring jobs and industry back onto American shores," Trump said.

The nation's meteorological agency had earlier estimated the quake's magnitude at 7.3.

Delhi High Court on 22 November will hear a plea against demonetisation which said once the currency was invalidated then how could the government direct certain public utilities including hospitals and petrol pumps to accept old notes.

A bench of Justices B D Ahmed and Jayant Nath listed for hearing tomorrow the plea which also sought discontinuation of the new Rs 2,000 currency note, terming the move as "unconstitutional and bad in law".

Petitioner Pooja Mahajan, running a designer showroom, mentioned the matter pleading urgency on the ground that she is being deprived of earning her livelihood and her fundamental rights are being infringed.

She also blamed the government for taking a dual stand saying on one hand it was encouraging people to deposit old notes in bank accounts and on the other hand threatening them of prosecution for depositing over Rs 2.50 lakh.
