Chris Eubank has said he wants to be charged by police after answering bail over an anti-war protest in London.
Eubank voiced opposition to Tony Blair's foreign policy
The former world champion boxer, 40, from Hove, East Sussex, was re-bailed to 22 May when he attended Charing Cross police station on Thursday.
Eubank was arrested on 22 February when he drove his truck around Whitehall, with a message attacking Prince Harry's deployment to Iraq later this year.
He used the same truck but with a new message when he answered his bail date.
'Catastrophic illegal war'
It said: "Mr Blair, look after our people and our country.
"Your foreign policy creates terrorism. Military occupation causes terrorism.
"As long as we elect you, do the things we want - security, healthcare, education, social security."
Eubank's latest display followed on from his original message in February, which said: "Blair, don't send our young prince to your catastrophic illegal war to make it look plausible."
On that occasion he drove his seven-tonne Peterbilt truck around Whitehall, but was arrested for allegedly breaching the peace, driving without due care and attention and staging an unauthorised protest.
'Not for publicity'
After being released on bail again on Thursday, he told reporters: "I want the police to charge me and I want Tony Blair to be impeached.
"I am a public figure and this is about keeping it in the news.
"If Prince Harry goes to Iraq, it's ridiculous."
Eubank's solicitor, Mark Stephens, denied his client was just courting publicity, saying he was "behaving as a responsible citizen".
