31st (City of London) Signal Regiment (V) was a Territorial Army regiment in the Royal Corps of Signals in the British Army. The Regiment previously formed part of 2 (National Communications) Signal Brigade, providing military communications for national operations. However, as at 31 March 2010, along with 5 other TA signal regiments, the regimental HQ has finally closed with the loss of two squadrons (reduced to troop size) and the move of its two other squadrons to other signal regiments. Notably, 41 Signal Squadron has been reassigned to 38 (City of Sheffield) Signal Regiment.
