Memes have been taking over the internet as the UK begins the process of leaving the European Union.

Memes are widely being shared on social media after the UK submitted its formal notice of leaving the EU.

Some opposed to the start of the Brexit process, by circulating images saying that this would bring the demise of Britain.

Many people shared memes to show their happiness about the historic day. This one shows actor Alastair Sim as Ebeneezer Scrooge in a scene from A Christmas Carol with a twist to the famous quote in the film.

And one was keen on shortening the process that could take up to two years: "Could the government use Amazon to deliver Article 50...next day delivery, please."
