An official freezing of diplomatic ties with Modi had been initiated under the Labour-led government in the aftermath of the 2002 Gujarat riots.
However, the party leadership has recently been making several overtures to reinstate ties with Modi, who if exit polls prove to be correct could take over as the new Prime Minister.
Labour Friends of India chairman and MP Barry Gardiner had tried to set the ball rolling with a letter inviting Modi to the House of Commons to speak on “The Future of Modern India” last August.
