 There had been concerns in the British media about serviceability of the Nimrod fleet and bereaved families having to wait for years for the Oxfordshire coroner's office to hold inquests into military deaths.Conservative MP, Mr Ian Liddell-Grainger called for the MR2's replacement – the BAE MRA4 – to be introduced sooner.That aircraft suffered significant problems during development and construction which resulted in lengthy programme delays and the in-service date slipping nine years from 2003 to 2012.
