the house of commons две полоски

The two red lines on the floor of the House of Commons are 2.5 metres (8 ft 2 in)[20] apart, which, by apocryphal tradition, is intended to be just over two sword-lengths. It is said that the original purpose of this was to prevent disputes in the House from devolving into duels. However, there is no record of a time when Members of Parliament were allowed to bring swords into the Chamber; historically, only the Serjeant at Arms has been allowed to carry a sword, as a symbol of their role in Parliament, and there are loops of pink ribbon in the Members' cloakroom for MPs to hang up their swords before entering the Chamber. In the days that gentlemen carried swords, there were not any lines in the Chamber.[91][92] Protocol dictates that MPs may not cross these lines when speaking; a Member of Parliament who violates this convention will be lambasted by opposition Members. This is—incorrectly, given the relatively recent addition of the lines—regarded as a possible origin for the expression "to toe the line".
В двух словах: за линии нельзя выходить во время выступлений. Плюс куча неподтвержденных легенд и слухов.
