Our chief politicical commentator casts his eye over this week's Independent

In an article earlier this week we misattributed remarks about the complaints process in prison to Debra Baldwin, an official with the Ministry of Justice. We are happy to point out that the words were not hers.

In our article “Labour grandees warn Miliband to be more than a voice of protest” (14 April 2013), we wrongly identified John Prescott as one of those making criticisms of the Labour leadership, it was in fact David Blunkett. We apologise to Lord Prescott for our error.

On Monday we reported that Tom Groves, whose sister Sarah was killed in Kashmir last week, had expressed concern over approaches to the family by The Sun newspaper.  A spokesman for The Sun has disputed this account and said the paper’s reporter acted properly and sensitively, having made the same approaches as other media organisations.

Plus, a heads up on Google Glass: the Independent on Sunday's chief political commentator runs his rule over this week's coverage

In an article in last week’s Independent on Sunday (“Trinity Mirror executives need to face up to the murky past”) we said that a report gathered from former senior Mirror reporters was given to Trinity Mirror chief executive Simon Fox and chairman David Grigson.  Mr Fox and Mr Grigson have pointed out that they have not seen any such report and we are happy to acknowledge this and apologise to them.

Our peerless pedant examines the flaws in this week's Independent

On Saturday we reported that Balmoral Castle and Sandringam House are not open to the public (“Royal books face MPs’ scrutiny for first time”).  In fact, both offer access to visitors at certain times of the year.

In an article on health care in the Independent recently, the phrase ‘normalisation of cruelty’ was attributed to Ann Clwyd MP. In fact it is a phrase that has been used by the Health Secretary Jeremy Hunt. We are happy to clarify.
