Video: Nick Clegg puts forward 'final' amendments to NHS Bill In a letter to Lib Dem MPs co-signed with Baroness Williams - the most prominent critic of the reforms within the party - Mr Clegg endorsed what he called "final" amendments to limit competition in the health service. Commenting upon the letter, the Lid Dem leader said: "We want to see some final changes to the legislation, before its adopted, to ensure - to make crystal clear - that competition will always be the servant of the NHS, never its master." Downing Street indicated that Prime Minister David Cameron had been consulted on the letter and was happy to sanction further changes to the flagship Bill in order to provide "reassurance and clarity" to his coalition colleagues. The PM's official spokesman said the Government would not accept any more "significant" changes to the Bill, which has already been subject to numerous amendments after running into stiff opposition from health workers. But sources close to Health Secretary Andrew Lansley said he was "relaxed" about the changes sought by Mr Clegg, which he did not believe would substantially alter the impact of the legislation on the way the NHS operates. Labour dismissed the letter as a "panic move" by the Lib Dem leader to save him from confrontation with activists at the party's spring conference at the end of next week. It was a Lib Dem rebellion at the same gathering last year which prompted the Government to pause the legislative process and listen to critics' concerns.
