Ofcom is to reveal the findings of a financial review of Channel 4 in the spring.

In September, consultants from global firm LEK were appointed by the regulator to review "all aspects of (Channel 4's) financial statements, business plans and management accounts for the past five years", including the company's "future performance projections".

Channel 4 has argued that falling ad revenue and competition from digital media is hindering its ability to finance its public service broadcasting remit.

Following the review, an announcement is expected in the late summer about what necessary actions could be taken to assist the broadcaster.
