Surjit's brother Jagdeesh Singh told ITV News he has written to Prime Minister David Cameron asking him to put pressure on the Indian Government to reinvestigate the murder of his sister Surjit Athwal.
Ms Athwal was killed in India in 1998. Her mother-in-law and husband were convicted of ordering the killing but no one has ever been found of actually carrying out the murder.
MPs and peers will today pay their respects to Baroness Thatcher after Parliament was recalled from its Easter recess so tributes could be paid to the former prime minister.
They will debate a single line motion which reads: "That this House has considered the matter of tributes to the Rt Hon Baroness Thatcher of Kesteven LG OM."
The Prime Minister will lead the debate on the death of Lady Thatcher, Ed Miliband will follow, before Speaker John Bercow then calls MPs to contribute.
The order paper for proceedings indicate the debate may continue until 10pm, at which point Leader of the House Andrew Lansley will adjourn the Commons until its planned return from the Easter recess on Monday.
With the passing of Baroness Margaret Thatcher, the world has lost one of the great champions of freedom and liberty, and America has lost a true friend.
As a grocer’s daughter who rose to become Britain’s first female prime minister, she stands as an example to our daughters that there is no glass ceiling that can’t be shattered.
As prime minister, she helped restore the confidence and pride that has always been the hallmark of Britain at its best.
And as an unapologetic supporter of our transatlantic alliance, she knew that with strength and resolve we could win the Cold War and extend freedom’s promise.
Here in America, many of us will never forget her standing shoulder to shoulder with President Reagan, reminding the world that we are not simply carried along by the currents of history—we can shape them with moral conviction, unyielding courage and iron will.
Michelle and I send our thoughts to the Thatcher family and all the British people as we carry on the work to which she dedicated her life—free peoples standing together, determined to write our own destiny.
Downing Street has confirmed that Baroness Margaret Thatcher will be given a Ceremonial funeral:
Downing Street can announce that, with The Queen's consent, Lady Thatcher will receive a Ceremonial funeral with military honours. The service will be held at St Paul's Cathedral. A wide and diverse range of people and groups with connections to Lady Thatcher will be invited.
The service will be followed by a private cremation. All the arrangements being put in place are in line with wishes of Lady Thatcher's family. Further details will be published over the coming days.
The Prime Minister says the money to pay for HS2 will need to come from 'a balance' between the Government and 'the train user' - but expensive tickets are necessary for 'Britain to be a success'. See the full interview above.
