Andy Wilson, chief executive of Capital City College Group, is to retire this summer, Tes understands.
Prior to the creation of the group through merger, Mr Wilson was principal of Westminster Kingsway College for 12 years.
In a statement, staff unions at CCCG said they have supported a motion of no confidence in the chief executive. A recent staff survey exposed serious concerns among the vast majority of the staff about the leadership across the college group, they said. They added the survey reflected "a deep-seated unhappiness amongst staff due to a developing sense of crisis in many aspects of the group".
CCCG was created in August 2016 through the merger of Westminster Kingsway College and City and Islington College. Last year, it launched Capital City College Training (CCCT), a training arm providing workforce development support and around 100 apprenticeship programmes, and in November, the College of Haringey, Enfield and North-East London joined the group, cementing its place as the third biggest in the country.
Staff 'unhappy with leadership'
The group has begun the process to recruit a new chief executive, it has announced, and Mr Wilson will remain in post until his successor is appointed and takes up the position.
He said he was proud to have been part of the creation of CCCG, "and through it to have ensured its member colleges continue to flourish at the heart of further education and training in London". "I have been fortunate to work with a tremendous team of managers and governors and thank them for the support they have provided in steering the group through the first phase of its development" Mr Wilson said.
He added: "However, as we all know, further education operates in a fast-changing environment and I believe CCCG needs somebody who can make a longer-term commitment than I can as it moves through the next phases of its evolution."
