His exact leaving date has not been revealed, but the council says he'll still be looking after major developments "over the coming months".
It adds that the focus on Coventry being UK City of Culture in 2021 won't change.
Council leader questions latest Ricoh appeal
BBC Coventry & Warwickshire Sport
Coventry City Council leader George Duggins has called on the owners of Coventry City football club to explain "what they are hoping to gain" by taking the matter of the sale of the Ricoh Arena to the European Commission.
The club is making the move after being denied an appeal over the sale by the British courts, but owners Sisu claim the Ricoh was undervalued by £28m, and is asking the Commission to see if the deal breaks state-aid rules.
Coventry will play at St Andrew's in Birmingham next season after failing to agree a new deal with arena owners Wasps.
Coventry City's owner Sisu has taken its legal complaint to Europe after the Supreme Court threw out its appeal over a judicial review into the sale by Coventry City Council.
Sisu claims the Ricoh was undervalued by £28m, and is asking the European Commission to see if the deal breaks state-aid rules.
The European Union has rules on how much government money can be given to commercial enterprises to ensure one does not get an unfair advantage over another.
An EU spokesperson said: "The Commission has received a
complaint regarding the sale of the Ricoh Arena to Wasps Rugby Club and is
currently assessing it in line with its standard procedures."
Coventry City had been in talks to stay longer at the Ricoh Arena, but Wasps chief executive Nick Eastwood said the club had "entered such discussions in good faith" and that because the case had been taken to the EU, its conditions for negotiations hadn't been met.
English Football League clubs will discuss the issue on 29 May.
For those of you waking up, this is how the overnight election results have panned out in the West Midlands.
One of the big results saw the Conservative Party seize overall control of Walsall Council, taking two seats off Labour.
However, the party couldn't make enough gains to take Dudley Borough Council as it tied with Labour for the number of seats, although, with a Tory mayor, it has a casting vote when it comes to deciding later this month who'll lead the authority.
Elsewhere, the Tories lost their majority in Worcester but held on to North Warwickshire, Rugby and Tamworth.
Labour, meanwhile, held on to Coventry, Sandwell, Telford and Wrekin and Wolverhampton.
We're still waiting for the final result from Stoke-on-Trent.
