Thousands of people were protesting outside the Houses of Parliament against the result of the referendum of Britain's membership of the European Union, Sky News reported on Tuesday.

The protest appeared to be spontaneous and without apparent leadership, and groups of demonstrators were singing songs and chanting slogans, many of which were aimed at the leaders of the Leave campaign, according to the broadcaster.

The crowds gathered near the Houses of Parliament shortly after 5 p.m. local time, holding placards which read "Reunited kingdom", "Everyone is welcome here" and "let's hug it out", according to a report posted on the Daily Express website.

The size of the protest was much bigger than the pro-Corbyn demonstration held in Parliament Square on Monday night, and it looked like this is a segment of the population who signed up to that protest online, which had garnered three million signatures so far, calling for a debate in parliament and for a second referendum, Sky news reported.

A small rally of hundreds was earlier held in Trafalgar Square against Brexit, shortly after Labour Party MPs voted against Jeremy Corbyn in a motion of no confidence.
