Killed soldier Lee Rigby would not have wanted his death used to excuse reprisal attacks, his family have said.

Drummer Rigby's family called for calm as the Queen met army personnel during a visit to the barracks near where he died on 22 May.

In a statement, his family said his friends' different cultures and religions "made no difference to Lee".

The family's plea came amid reports of a sharp rise in anti-Muslim incidents since the soldier's murder in Woolwich.

Faith Matters, an inter-faith organisation aimed at tackling extremism, said it had recorded 212 incidents since last Wednesday, up from between four and six per day.

'Extremist organisations'

At the scene - Woolwich Barracks The Queen's visit to the Royal Artillery Barracks was long-standing and Buckingham Palace was keen for it to go ahead, despite last week's stabbing. Drummer Rigby, a member of the Royal Regiment of Fusiliers, was not based at Woolwich, but did live there. The MoD acknowledged that it had been "a tough week" for staff at Woolwich, but would not be drawn any further on how troops had been affected. The main purpose of the Queen's visit to Woolwich was to present medals to two soldiers from the largely ceremonial King's Troop, who have just returned from a tour in Afghanistan. But before lunch, she privately acknowledged Drummer Rigby's death by meeting a group of soldiers involved in coordinating the barrack's response to the attack, and some of those who formed part of his chain of command. The Palace said there would be no public acknowledgement of the stabbing, as the Queen's route to and from the barracks would not pass the floral tributes that have been left outside the main entrance to the barracks.

In a statement, Drummer Rigby's family said: "Lee would not want people to use his name as an excuse to carry out attacks against others".

"We would not wish any other families to go through this harrowing experience and appeal to everyone to keep calm and show their respect in a peaceful manner."

Drummer Rigby's regiment, the Royal Fusiliers, also issued a notice to veterans and serving soldiers warning them about being associated with far-right groups.

It said a number of retired soldiers had been approached to take part in demonstrations taking place in the wake of the soldier's death.

Brig Ian Liles, regimental secretary to the Royal Regiment of Fusiliers, said: "It is wrong and disgraceful that the death of one of our own should be exploited in this manner."

A separate notice issued by Army headquarters and passed on by Col James Stopford warned that "extremist organisations (the English Defence League in particular) will seize any opportunity to align veterans with their cause".

In other developments:

An inquest into Drummer Rigby's death was adjourned after hearing he was hit by a car and attacked with a knife and cleaver on his return to the barracks from work at the Tower of London. His family did not attend the brief hearing.

Police investigating the Woolwich attack arrested a 42-year-old man in north London on suspicion of involvement in the supply of illegal firearms.

Woolwich Mosque invited the community to share tea and biscuits after Friday prayers, an occasion which was also attended by the Bishop of Woolwich.

Police asked the British National Party to alter the route of a planned march from Woolwich on Saturday. Instead, it will be allowed to take place in Westminster.

The Queen's visit to Woolwich barracks to see the new home of the King's Troop Royal Horse Artillery was planned before the murder of Drummer Rigby.

Gun salute

At the scene - Woolwich Mosque The sun shone for the first time in days as tea and biscuits were served outside Greenwich Islamic Centre. Leaders at the centre, also known as Woolwich Mosque, had urged the community to drop in after Friday prayers. An inter-faith meeting also took place at the mosque. Erica Wooff, rector of Charlton, said tea and a chat was a simple but effective way to respond to the events of last week. "When words are impossible, the only way to respond is with actions. And what better way than with a cup of tea," she said. Locals Caz Shane, 70, and Fazilah Brooke, 55, who chatted animatedly over an orange juice, had not met before today. "The more people who come the better so we can all get to know each other," said Mrs Brooke. Mrs Shane added: "I wanted to be here to say to the EDL and others, 'I'm not with you'."

But the monarch paid her respects to the soldier by meeting officers and soldiers associated with him in private, before having lunch in the Sergeant's Mess.

She met Lieutenant Colonel Bob Christopher, commander of Woolwich Station, and his team, as well as staff from the Royal Regiment of Fusiliers' outreach team, Drummer Rigby's regiment, based at the Tower of London.

Her tour of the base was hosted by the commanding officer of the King's Troop, Major Mark Edward.

The regiment, which is a largely ceremonial one, is famed for firing gun salutes on royal anniversaries and state occasions, and for providing a gun carriage and a team of black horses for state and military funerals.

Baroness Thatcher's coffin was carried on a gun carriage from the King's Troop during her recent funeral, and on Monday the unit will fire a 41-gun royal salute from London's Green Park to mark the 60th anniversary of the Queen's Coronation.

During her visit, the Queen watched a gun team display in the riding school and visited the horses' stables, the forge where they are shod and the veterinary clinic.

She also presented medals to two members of the King's Troop - Lance Bombardier Dannielle Parker, 25, and Warrant Officer Second Class Jeremy Faulkner, 36 - who have recently returned from a tour in Afghanistan.

The Queen's journey to the barracks in south-east London did not take her past the scene of Drummer Rigby's murder, where thousands of flowers have been laid by members of the public in his honour.

Michael Adebowale, 22, of Greenwich, has been charged with his murder and appeared before Westminster magistrates on Thursday.

A second suspect, Michael Adebolajo, 28, remains under arrest at a London hospital where he is being treated.

Both men were shot by police before being arrested.

In total, police have arrested nine other people in connection with the investigation so far; six of these have been bailed and two released without charge.
