Macron plans to slash France’s MPs by a third

French President Emmanuel Macron has pledged a "profound transformation" of French politics, proposing to slash by a third the number of MPs, and telling lawmakers he would call a referendum if they do not agree.

In his first address to members of the National Assembly and Senate since his election in May, Macron delivered a US-style state of the nation speech in the Versailles palace, the former seat of French kings, arguing that the country must change.

"Until now, we were too often on the wrong track,” he said. "We preferred procedures to results, rules to initiative, a society where you live off inherited wealth, to a just society."

He confirmed a plan to implement a reform of France's political system, changes first raised during campaigning.

These include slashing the number of MPs in both houses of parliament - 577 in the lower house National Assembly and 348 in the Senate - by a third, saying it would have "positive effects on the general quality of parliamentary work".

Macron also pledged to introduce a degree of proportional representation into France's winner-takes-all electoral system.

He said that the move, long demanded by small parties such as the far-right National Front, would ensure "all tendencies are fairly represented”.

The centrist president, who enjoys a large majority in parliament, said he hoped lawmakers would adopt the changes within a year but reserved the right to organise a referendum "if necessary".

Macron's decision to convene a sitting of both houses of parliament - a rare event usually reserved for times of crisis - was criticised by the opposition, who described his use of Versailles as further proof of a "monarchical" drift.

The speech was Macron's first major address in France since his inauguration in mid-May, when he promised to lead a "renaissance."

He warned the newly-elected lawmakers against triumphalism in the face of the "gravity of the circumstances" both in France, which is grappling with a stagnant economy, and in Europe which had "lost its way".

"The building of Europe has been weakened by the spread of bureaucracy and by the growing scepticism that comes from that," Macron said.

"The last ten years have been cruel for Europe. We have managed crises but we have lost our way," he said, adding that France would help drive a revival of the European idea of "social justice".
