Watch: Former postal affairs minister Ed Davey questioned at Horizon IT inquiry

Watch as Sir Ed Davey gave evidence to the Post Office Horizon IT inquiry on Thursday, 18 July.

The Liberal Democrat leader previously served as a minister with responsibility for postal affairs in the coalition government with the Conservative Party.

More than 700 subpostmasters were prosecuted by the Post Office and handed criminal convictions between 1999 and 2015 as Fujitsu’s faulty system made it look like money was missing at their branches.

Another former postal affairs minister, Labour's now Chancellor for the Duchy of Lancaster Pat McFadden, told the inquiry he wished he'd done more to ask the Post Office if the faulty system was “as robust as they suggested”.

Sir Ed has previously apologised for his role as a minister in the Horizon scandal, saying he was “sorry I did not see through the Post Office’s lies”.
