The murdered soldier has been named as Drummer Lee Rigby of 2nd Battalion Royal Regiment of Fusiliers. He was aged 25.
Tragically, Lee leaves behind not only a wife but also a two-year-old son named Jack.

Lee was from the Middleton area of Manchester and he joined the army in 2006. He had served in Afghanistan, Germany and Cyprus, yet he was killed in a street in his own capital city.
Most of the rest of Drummer Lee's battalion are curently in Afghanistan but he was at the Woolwich Barracks because he took up a post with the Regimental Recruiting Team in London in 2011.
Capt Alan Williamson said: "Drummer Rigby or 'Riggers' as he was known within the platoon was a cheeky and humorous man, always there with a joke to brighten the mood."
Defence Secretary Philip Hammond said: "This was a senseless murder of a soldier who has served the Army faithfully in a variety of roles including operational tours in Afghanistan.
"Our thoughts today are with his family and loved ones who are trying to come to terms with this terrible loss."
Mr Hammond was asked if the attack showed how vulnerable soldiers were, whether they were in uniform or not.
He replied: "I think it reminds us how vulnerable we all are, but it also reminds us, by the response of the public, that we are not going to be cowed by this kind of terrorist action."
Chief of Defence Staff General Sir David Richards said: "It's always a tragedy, it's particularly poignant that it happened on the streets of this capital city of ours.
"We're absolutely determined not to be intimidated into not doing the right thing - whether it's here in this country or in Afghanistan or wherever we seek to serve the nation."
The Ministry of Defence also paid tribute to Drummer Rigby.
"An extremely popular and witty soldier, Drummer Rigby was a larger than life personality within the Corps of Drums and was well known, liked and respected across the Second Fusiliers.
"He was a passionate and life-long Manchester United fan."
Career: Drummer Rigby, 25, known as 'Riggers', was known as a brave soldier
The bereft family of executed soldier Lee Rigby today described him as 'our hero' and said: 'We loved you so much, you didn’t deserve this'.
His estranged wife Rebecca, mother of his son Jack, two, revealed the former couple had agreed to meet this weekend to 'continue our future together as a family' before his life was brutally taken away in Woolwich, in the Royal Borough of Greenwich, south east London, on Wednesday.
Mrs Rigby burst into tears as she said she never dreamed that her husband might be killed in Britain, adding: 'You think they’re safe.'
Lee's stepfather Ian Rigby added: 'When in Afghanistan, you come to terms with it, you know it’s dangerous, you don’t expect something like that on your doorstep. It’s very difficult'.
He also sobbed as he described how he found out about the killing on TV and tried to contact his step-son immediately.
'Really as soon as it came on the news on television, obviously we didn’t know it was Lee but your heart skips a beat when you see something like that on TV, you know your son is in that area,' he said.
'As soon as it was on the telly we were attempting to get hold of Lee, obviously we couldn’t and it was the middle of the night probably when we got confirmed to us it was Lee.'

The family paid tribute during an emotional press conference at the Regimental HQ of his unit, the Royal Regiment of Fusiliers in Bury, Greater Manchester.
Machinegunner Rigby, who recently served in Afghanistan, was hacked to death in broad daylight by Islamist fanatics as he walked back to Woolwich Barracks in south-east London, where he was stationed.
Two men, Michael Adebowale, 22, and Michael Adebolajo, 28, are believed to have carried out the atrocity and are under arrest in separate London hospitals after being shot by armed police.
'I love Lee and always will. I am proud to be his wife and he was due to come up this weekend so we could continue our future together as a family,' his wife Rebecca said today.

Asked about the shock of the attack being on British soil, she added: 'You don’t expect it to happen when he’s in the UK.'
Lee’s stepfather Ian read out a statement on behalf of and prepared by the whole family.
'What can we say about Lee, our hero, we are so so proud of Lee,' he said.
'When Lee was born the family adored him, he was a precious gift given to us.
'Lee had a fiery temper when he was younger, I used to sit on him to calm him down till he got too big at 15, then he used to sit on me.
'Lee’s dream growing up was always to join the army which he succeeded in doing, he was dedicated and loved his job.'
He also read Lee's last text to his mother Lyn, Ian's partner, sent on an evening before his death which said: 'Goodnight mum, I hope you had a fantastic day today because you are the most fantastic and one in a million mum that anyone could ever wish for.'
Adebowale and Adebolajo are recovering in separate hospitals under armed guard after being shot by armed police officers, who fired eight shots. The police shot to wound them rather than kill them in order that the two murderers can be brought to justice. They should probably expect to spend the rest of their lives in prison.
Murderer: Michael Adebowale, 22
At least two other people are being questioned by police. One of them is Adebolajo's sister, Blessing Adebolajo, 32, who gave a bizarre grin as she was put into an unmarked police car outside her home in Romford, north east London. She was carrying a bag of clothes as she got into the vehicle at 8.10am.

It is understood she was not arrested, but police will undoubtedly want to question her about her brother who neighbours said was seen regularly at the house.
A woman purporting to be Adebolajo's sister told the Romford Recorder newspaper yesterday: 'We didn't know he was going to do this.'
The killing of an off-duty soldier in a brutal attack in broad daylight on a London street has shocked the nation, inspiring hundreds of strangers who had never met him to leave poignant tributes.
Many of the tributes came from veterans, fellow servicemen and women and their families. One moving notecard left at the scene said: 'To a brave young soldier, God bless, rest in peace, from an old soldier.'
William Pemberton, whose son Billy took his own life after being the youngest soldier to serve in Afghanistan, left his own poignant note describing the two fallen soldiers as 'brothers'.
Others were from members of the public who had no connection to Drummer Rigby but wanted to express their sadness at the attack and give sympathy to his family.

A prayer service for Drummer Lee Rigby, the soldier killed by two assailants in south-east London on Wednesday, has taken place in Greater Manchester.

The prayer service saw people from the Langley estate gather in All Saints and Martyrs' Burnside Community Centre.
Jim Dobbin, the Labour Co-operative MP for Heywood and Middleton, said Drummer Rigby's death had "absolutely traumatised" people on the estate.
The Reverend Philip Miller, who led the service, said it had been a chance to "support the Rigby family".
"Obviously, it is incredibly hard for them but these lovely people need to know that they are supported [by the community]."
He said it was important for "everybody to respect the family's privacy".
People who attended the service, which included prayers and readings, lit candles in memory of Drummer Rigby.
Floral tributes have been left in the garden of the Rigby family's home on the estate, where the soldier grew up.
