- Adebowale jailed alongside Michael Adebolajo for killing Fusilier Lee Rigby
One of Lee Rigby's killers has sparked outrage after being allowed to write letters to a pen pal urging him to convert to Islam and advising him on jihad while moaning about prison food, it is claimed.
Michael Adebowale, 24, who is currently at HMP Wakefield, West Yorkshire, after being jailed for life for the killing of Mr Rigby, told his pen pal to embrace Islam, adding: 'Allah has blessed me a lot.'
Adebowale, a former Christian, also urged his friend to read a chapter in the Koran that tells the faithful to fight 'disbelievers' and 'kill them wherever you find them', while telling him that prison food 'ain't so good'.

Adebowale was jailed alongside Michael Adebolajo, 32, for murdering Mr Rigby with a meat cleaver and knives near the Royal Artillery Barracks in Woolwich, south east London, in May 2013.
They knocked Mr Rigby down in a car as he walked towards the barracks and then hacked him to death.
Mr Rigby's father, Phil McClure, has now hit out at the prison service claiming the letter by Adebowale should never have been allowed to be sent.
The 55-year-old told The Sun: 'How can he be preaching about Islam to a pen pal? He should have lost all his rights.
'It makes me sick. I thought his letters were supposed to be read before they were sent? Someone must take the blame for this.
'He's lucky to be alive never mind moaning about his prison food.'
Both of Mr Rigby's attackers were found guilty of murder and sentenced to life imprisonment.
Adebolajo was given a whole life order and Adebowale was ordered to serve at least 45 years.
Adebolajo has previously complained about being segregated from other Muslim prisoners.
He was moved from HMP Belmarsh in Thamesmead, south east London, to Frankland in County Durham after fears that he was trying to radicalise other inmates.

He wrote to support group Muslim Prisoners who said: 'The guards at Frankland are worse than Belmarsh for treatment of Muslims. This move is deliberate.'
He is now trying to seek compensation from the taxpayer after his teeth were knocked out in prison.
He lashed out at officers who were trying to escort him to his cell in July 2013 and, during the scuffle, his head reportedly hit a window. He refused medical attention afterwards but is now trying to sue the Prison Service.
Adebolajo and Adebowale were raised as Christians but described as British Muslim converts at their trial.
Adebowale had openly discussed murdering a soldier on Facebook, but that information had not been passed to the intelligence services.
Adebolajo issued a series of threats to the West after the bloody murder took place. A shocking video of him was taken on a mobile home while he ranted with a bloody machete in his hand.
The Ministry of Justice said letters featuring inappropriate content would be investigated.
A spokesman said: 'If anyone is in possession of inappropriate correspondence, we encourage them to pass it on to us so we can investigate fully.'
