squadrons in 11 Group knew that they would be in constant action, while pilots and squadrons transferred from No.11 Group knew that they were going to somewhere comparatively safer. During the Battle of Britain, the Group was commanded by New Zealander Air vice-marshal Keith Park. While supported by the commanders (AOCs) of No. 10 Group and No. 13 Group, he received insufficient support from the AOC of 12 Group, Air Vice Marshal Trafford Leigh-Mallory, who used the Big Wing controversy to criticise Park's tactics. Leigh-Mallory's lack of support compromised Fighter Command at a critical time and the controversy caused problems for Park. When the Battle of Britain was over, Leigh-Mallory, acting with Air marshal Sholto Douglas, conspired to have Park removed from his position (along with the Commander-in-Chief of Fighter Command, Air chief marshal Hugh Dowding). Leigh-Mallory then took over command of 11 Group. Post-war After the war in December 1951, No.11 Group consisted of the Southern and Metropolitan sectors. The Southern Sector included 1 Squadron and No. 29/22 Squadrons at RAF Tangmere and 54 Squadron and 247 (China-British) Squadron at RAF Odiham. The Metropolitan Sector had 25 Squadron at RAF West Malling, 41/253 Squadron at RAF Biggin Hill, 56/87 Squadron and 63 Squadron at RAF Waterbeach, 64 Squadron and 65 (East India) Squadron at RAF Duxford, 72 Squadron at RAF North Weald, 85/145 at RAF West Malling with Gloster Meteor NF.11s, and 257 (Burma) Squadron and 263 (Fellowship of the Bellows) Squadron at RAF Wattisham. Denoted by a '/', a short-lived RAF postwar scheme saw several squadrons linked, where two squadron numbers' heritage was carried on within one single unit. In 1960 Fighter Command was re-organised and 11 Group was disbanded on 31 December 1960, to reform one day later when 13 Group was renamed 11 Group. On 1 April 1963, the Group was replaced by No. 11 (Northern) Sector at RAF Leconfield which controlled Fighter Command airfields and units within Northern England. On 17 March 1965 the sector absorbed No. 13 (Scotland) Sector RAF which was formed on 1 April 1963 at Boulmer and 11 Sector moved to Boulmer. This incarnation lasted until Fighter Command was absorbed into the new Strike Command on 30 April 1968 and became 11 Group. 11 Sector became Sector South and No. 12 Sector RAF was absorbed and became Sector North. Group Headquarters shifted to RAF Bentley Priory in north-west London and took
