A senior Met Police officer has been moved from his role following the publication of a report into Stephen Lawrence's murder investigation.
Almost 21 years after Stephen Lawrence was stabbed to death, the Home Secretary has ordered a public inquiry into undercover policing .
Stars including Rita Ora, Beverley Knight and Jessie J have played a tribute concert marking 20 years since Stephen Lawrence's death.
Stephen Lawrence's mother Baroness Lawrence fought back tears in the House of Lords as she said she and her family had endured "21 years of struggle" and there was "still more to come" following a review into the original investigation into her son's murder.
Scotland Yard deputy commissioner Craig Mackey said police would be "saddened" and "shocked" by the findings of the Ellison report:

There can be no serving police officer today who will not be saddened, shocked, and very troubled by what the Home Secretary has said, and the conclusions that Mr Ellison has reached.
He insisted that "corruption has no place in the Met Police":

A public inquiry into the operation of the SDS and undercover policing, whilst challenging because of its very nature, represents a real opportunity to provide the public with as complete a picture as possible of this unit, how it came to be and the hugely different policing context it operated within.
Corruption has no place in the Met Police - and people need to know that they cannot hide behind the veil of the past.
Former SDS officer Peter Francis said he was "delighted" by the news that a judge-led public inquiry will be held into the work of undercover police.
"I have been calling for such an inquiry since October 2011," he said.
"When the full truth comes out about the Police's work and activities, across the UK, against political campaigns and protests since 1968, I think they will be very shocked.”
A spokesperson for Boris Johnson, Mayor of London, said: "The Mayor's Office takes the findings of the independent Ellison Review very seriously and we intend to take the time to digest the report in full.
"The report contains profound and disturbing findings related to the Stephen Lawrence investigation and subsequent inquiries. All allegations must be investigated fully and those responsible held to account.
"We recognise the serious impact these findings could have on public confidence in the police, and it is essential we have a Met police that is trusted and respected by all Londoners."
Labour politicians have expressed their shock over allegations of police corruption contained within the Stephen Lawrence Review.
Deeply shocking conclusions from the Ellison Review into Stephen Lawrence case. Important to get truth and justice for Doreen and family
Ellison review findings on corruption & undercover operations in investigation into racist murder of Stephen Lawrence are deeply disturbing
Truth & justice needed for Lawrence family - & for the sake of confidence in vital work police do. No family should have to wait 21yrs
The mother of Stephen Lawrence, who was murdered in 1993, told ITV News she still does not trust the Metropolitan Police after a review into the police inquiry looking at her son's death uncovered evidence of corruption.
When asked whether black people could trust the force, Doreen Lawrence said: "This is going to put another nail in their coffin, definitely not, you just can't trust them,"
There is evidence to suggest that Detective Sergeant John Davidson acted corruptly during the murder investigation of teenager Stephen Lawrence, the Ellison review has found.
Mark Ellison QC said there was a high level of suspicion that the former officer was corrupt both before and after he worked on the police investigation.
The Ellison report said that in July 1998, Scotland Yard's Anti-Corruption Command heard claims made against Mr Davidson, but they were not shared or revealed by the public inquiry into police racism led by Sir William Macpherson in the wake of Lawrence's murder.
Mr Ellison said that, while independent corroboration of some of the allegations did not currently exist, there were "outstanding lines of inquiry" that could be investigated, which may change that assessment. He added:
"It is not impossible to envisage that the inquiry might have been driven to the conclusion that there must have been more to John Davidson's failure to develop information and evidence in the Lawrence investigation than simply an inappropriate manner and unfortunate unconscious racism".
Doreen Lawrence, the mother of Stephen who was murdered in 1993, told ITV News the revelation that the Metropolitan Police had placed a spy in the family camp was "really disgusting."
The mother of Stephen Lawrence told ITV News it was a "disgrace" that the Metropolitan Police were "spying" on her family when they were mourning the loss of their son.
Doreen Lawrence added that all the family wanted "was to catch Stephen's killers" but it was clear the Met "had a different agenda."
Ms Lawrence's comments come after a report into the police inquiry into the murder of Stephen uncovered evidence of corruption.
Details have emerged on allegations of police corruption as outlined in the Stephen Lawrence review. The report, published by the Home Office, paints an "intelligence picture" which suggest "corrupt activity" among a "number of officers".
