Nigel Farage has called for an overhaul of the political system, claiming the current structure makes Westminster "incapable of change".
The Brexit Party leader said the result of the EU referendum had highlighted issues with the two-party system, which he says is "not actually fit for purpose".
"We have reached a moment where the UK has got to get into the 21st Century," he told talkRADIO's James Whale.
"Let's have a form of government that is directly accountable to the people, and let's be excited about making that change."
Among the changes he proposed was the abolition of the House of Lords, and a radical revision of the current voting system.
"We have to reform the voting system to make it much more representative of the country," Mr Farage continued.
"What an outrage that 700 of Tony Blair and David Cameron's mates sit in the House of Lords. They all live in Kent and Chelsea, the whole thing is ludicrous, so that has got to go. We have to have an elected upper chamber."
The politician accused MPs of "fighting like cats and dogs" over the referendum result.
"What the world sees is our Westminster Parliament arguing, fighting like cats and dogs with a democratic decision that has not been delivered.
"We are a global laughing stock."
