Economic recovery has led to a doubling of viewings of vacant space at London’s Canary Wharf complex by prospective tenants in the first half of this year compared with the previous six months, according to its landlord Songbird Estates, the UK-listed property company.

Leasing proposals have been made to 24 companies in the three months to June. Seven comprised inquiries for more than 100,000 sq ft, six for 30,000-100,000 sq ft and 11 for less than 30,000 sq ft.
