History demonstrates why a new pro-EU party would be doomed

Churchill saw a century ago that the existing party machines will always prove the stronger, and UKIP and the SDP have confirmed this.

Kieron O’Hara: How liberalism can undermine the foundations on which it is built

Put harshly, it can be the ideology of the free-rider, the citizen who neglects the demands of citizenship.

Garvan Walshe: This election has brought Putin’s prize – a Far Left-led Britain – too close for comfort

It is now necessary to consider a strong and structured security partnership with the EU that would withstand the rule of Russia’s useful idiot.

Nick Mutch: Bear hugs, scowls, farcical handshakes – and a country that wasn’t there. What I saw at the NATO summit.

A first-time impression of a NATO summit – one that seems to have been uniquely designed with the American President’s “interests and eccentricities in mind”.

Ben Roback: Trump has banished Comey, but his Russia problems will prove harder to dispel

The President’s decision has aroused concern in both parties, and drawn attention once again to an issue he is desperate to shake off.

Regime change in Syria. Through diplomacy, yes – if possible. Through war, no.

The Government seems to get the message, but Conservative MPs should be vigilant. An Islamist government in Damascus would be in neither Syria’s interest nor ours.

Iain Duncan Smith: At long last, the USA has shown clear commitment to act against Assad

Obama’s desperate and impotent decision to abandon the Middle East to the Russians is being overturned. Not before time.

Britain must not be drawn into the civil war in Syria

Let’s hope that Trump’s missile strikes on the Assad regime work. But May and her government must be a force for restraint if they don’t.

The majority of Tory members believe Putin’s Russia is an enemy of the UK

The minority who believe Russia is an ally against Islamist extremism were outnumbered more than three to one.

Daniel Kawczynski: Yes, “engage but beware” really is the right policy for relations with Russia

Our bilateral relationship is at its most strained since the end of the Cold War. But we should try none the less to work with the country on as many levels as possible.

Is Putin’s Russia an enemy or ally? Please take our monthly survey.

Plus: Is Hammond’s deficit reduction strategy right? Is Trump a good or bad thing? And should May call a snap election?

Garvan Walshe: Trump threatens the security of the Nordic nations

They have the capacity to make a larger contribution to Europe’s defence. They should do so.

There should be no room for Putin apologism on the right

The fantasy that the Kremlin is more sinned against than sinning was once the preserve of Corbyn’s hard left. We should stop the rot.

James Frayne: Just how good is Russian propaganda?

It’s often been overrated, but its pre-war golden age bears striking similarities to Putin’s approach today.

Rebecca Coulson: Watch Trump like a hawk. Focus on the essentials. Judges should restrain him, women should sue him.

Watch what he says, and what he does – not what we think he means, represents, or how he comes across.
