Hollywood star Keanu Reeves caused a Twitter meltdown after he was pictured wandering around Parliament.

Reeves, 51, was spotted posing for selfies at Portcullis House on Tuesday – but no one seemed to know why he was there.

After a turbulent week in British politics, Reeves’ visit to Westminster apeared to lift the publics’ spirits with some joking that the actor had arrived to “save us” after Brexit.

Twitter users called for Reeves to be ‘put in charge’ while another called for him to take over as Prime Minister following David Cameron’s resignation.

Others couldn’t resist cracking jokes about Brexit with one tweeting: “Keanu Reeves is in Parliament to film his upcoming movie 'The Matrixit'.”

Ed Vaizey, Minister of State for Culture and the Digital Economy, also joked: "#Brexit explained - it's the matrix."

Sky reporter Beth Rigby said the actor was invited to Parliament as a guest of Conservative MP for Stratford-on-Avon, Nadhim Zahawi, although it is unclear what for.

Reeves is currently working on Bill & Ted 3, which is rumoured to be set largely in London, so he could have been visiting the capital ahead of filming.

Conservative MP Mark Pritchard appeared to confirm this, tweeting: “Met Keanu Reeves today to discuss expanding film production in west midlands not just in London.”

Fans have been awaiting a sequel in the cult franchise, and Reeves recently revealed that a script is in the making.

“We’re closer and we’re not closer,” he told IGN. “We’re expecting another draft and hopefully we’ll get closer.”

The new film will follow on from 1989's Bill & Ted's Excellent Adventure and 1991's Bill & Ted's Bogus Journey which starred Reeves as Ted Theodore Logan alongside Alex Winter as Bill S. Preston, Esq..
