Jan 13 (Reuters) - Boaz Weinstein's Saba Capital, which

holds about a ‌13.5% stake in London-focused flexible

office-space provider Workspace, ​sent a letter on

Tuesday urging the ‍company to pursue a managed ⁠wind-down.

"Considering the ⁠company's (Workspace) persistent trading

discount, refinancing challenges, and structural ‌impediments in

its shareholder base, ​the current model no longer represents the

best path to value ⁠creation," U.S. ‍activist investor ​Saba said

in the letter.

Saba also accused Workspace of having a highly ‍concentrated

shareholder register, with a small number of holders controlling

a "disproportionately large portion" of the shares.

The London-listed company's shares had fallen 7.6% in the

last 12 ​months ‍as of Tuesday's market close.

Workspace did not immediately respond to ​a Reuters request

for a comment.

The British firm reported a pretax loss of 71.1 million

pounds ($95.46 million) for the six months to September 30 as

budget uncertainty led to ​delays in leasing decisions by small-

and medium-sized businesses.
