Ahead of the inquest, Pam Duggan, Mark's mother, said: "Since Mark was shot dead over two years ago we have been provided with nothing but lies, misinformation, and delay.
"We hope that the truth will finally come out for the sake of all his family, not least his young children."
In January this year, when the inquest was delayed until September, counsel to the inquest Ashley Underwood QC said some of the issues for the inquest to determine include:
- What was the intelligence about the pistol, including its whereabouts and Mr Duggan's intentions about it, prior to him picking it up?
- Why was it not seized from the man who is said to have supplied it before Mr Duggan picked it up?
The inquest into the death of Mark Duggan who was shot by armed police, sparking a wave of riots across the country, is due to begin today.
More than two years after the father-of-four died, the full inquest into his death at the hands of Scotland Yard marksmen is expected to open at the Royal Courts of Justice.
Mr Duggan, 29, was killed when he was shot by police who stopped the taxi in which he was travelling in Tottenham, north London, in August 2011.
There has been speculation that he was on his way to carry out a revenge killing for his cousin's death at the time.
A mayor has apologised after she said 2011's riots were "the best thing that's happened" in her community for a while.
Sheila Peacock's comments about Tottenham - dubbed the "epicentre" of the riots two years ago - have upset residents who were forced to flee as homes and businesses burnt.
In an interview for a documentary, the mayor of Haringey - which includes Tottenham - said: "The second riots that we've just had was the best thing that's happened in Tottenham for a while.
"My reason for saying that is all of a sudden the government is now starting to pump money into Tottenham.
"Because Haringey is an out-of-London borough, so we don't get as much money as Islington or Hackney."
Just one in 13 foreigners who took part in the riots of 2011 have been deported, it emerged today.
More than 200 foreign criminals were convicted for their part in the riots, which saw shops looted, businesses burnt to the ground and hundreds of millions of pounds of damage done.
Of the 201 cases passed to the UK Border Agency (UKBA), only 15 have been kicked out the country, showed figures released to the Daily Mail following a Freedom of Information request.
Immigration Minister Mark Harper said: "Any foreign national who abuses the privilege of coming to the UK by committing a serious offence should face the consequences.
"Many of those convicted of involvement in last summer's riots are still behind bars - that's where they belong. We are pursuing deportation in scores of cases and wherever possible, when they have paid their debt to society, we will remove them from the UK."
Two men jailed for robbing a Malaysian student during the London riots have had their convictions for robbery and violent disorder overturned at the High Court.
The court accepted 24-year-old Reece Donovan and John Kafunda were both wrongly identified as the men who robbed Ashraf Rossli.
CCTV footage of a group of men pretending to be 'Good Samaritans' in order to steal from the injured student during last year's rioting caused widespread outrage.
Both Donovan and Kafunda have spent 16 months in jail.
The arrest of leaders of criminal gangs in the wake of last year's riots has led to an increase in "chaos, violence and anarchy" in neighbourhoods across the country, a report claimed.
Prime Minister David Cameron promised an "all-out war on gangs and gang culture" following the riots which brought mayhem to many English cities in the summer of 2011, and police have responded by arresting many of those associated with criminal groups.
But the report by the Centre for Social Justice, obtained by The Observer ahead of its publication on Monday, found that the removal of established gang leaders has led to the breakdown of criminal codes of behaviour and a "marked increase" in violence.
Many in Whitehall regard the riots as a random one-off, and mistake the quashing of the disorder as control of the streets. They could not be more wrong.
The alarming fact is that many streets across the country are besieged by anarchy and violence. There is no control in such neighbourhoods.
Mark Duggan, whose death triggered rioting across England, had a loaded gun when police shot him dead, Snaresbrook Crown Court has heard.
I've been in court today as sixteen people were sentenced for their role in the riots of London last year. They were sentenced to more than 70 years between them.
The judge said they went on a "journey of destruction" through the streets.
The prosecution described it as a campaign of violent disorder, burglary, and assault in Queensway and Notting Hill. Two rival gangs "put aside their differences" to join together in criminality. Shops were looted and shop owners attacked. The judge said:
"It was a year ago today that you were involved in this mob criminality that so disturbed the law-abiding public.
Today in stark contrast to the scenes of arson, looting and damage, London is hosting the Olympics which demonstrates the excellence which can be achieved in sport and is an inspiration to all. However those involved in these events were intent on doing the opposite."
A service will be held today to mark a year since the death of a man who was shot dead by police before the London riots.
A year and a day after the death of Mark Duggan in Tottenham, north London, members of his family are expected to attend a "service of hope" during what is being billed as a Day of Remembrance "to reflect on the events in the year since the shooting".
The event at Tottenham Town Hall comes after Mr Duggan's mother, Pam Duggan, made a fresh plea for justice for the family.
Mrs Duggan, whose son was shot in the torso by Metropolitan Police as they swooped on a car he was travelling in, said: "The past 12 months have been terrible."
