Moody's investor service was the first one to yank the country from its AAA rated list of countries back in 2013 but now other two have joined in too, since the referendum result. Fitch has cut its credit rating for the UK, from AA+ to AA on Monday, an action that was followed by the last major credit rating agency Standard & Poor. The group reduced the rating by two notches from AAA to AA. The move, however, was widely expected, since the rating agencies have warned to do this if UK votes to leave the Union.
