IWG is trying to strong-arm landlords into offering more favourable terms.
The co-working giant has filed notice of its intention to appoint administrators to subsidiaries holding the leases to its offices in Broadgate Tower and St Mary Axe in the City, as well as Covent Garden, Pall Mall and Chiswick.
IWG last year placed a Jersey subsidiary into administration, in effect dissolving guarantees on about 500 leases.
The company recently wrote to landlords of Spaces, its more upmarket flexible office brand, demanding improved lease terms.
