Sir Julian Brazier is a former Defence Minister, and was MP for Canterbury from 1987-2017.

After the horrific explosion in Beirut last month, the dust has cleared and the world has moved on, but Lebanon matters to Britain and the West. It is at a critical junction: on the one hand, offering substantial commercial opportunity, but with the spectre of destabilising an important and dangerous region, on the other. Britain is well-placed to help steer Lebanon on the right path by building on some excellent work already in train.

Why does Lebanon matter? The country is a temporary home to nearly two million Syrian refugees, the largest concentration in the Middle East, and these people will be on the move westward if Lebanon melts down. Thanks to David Cameron, Britain is a lead provider of aid to their camps, but the geo-strategic issues and opportunities go far beyond refugees and aid.

The country sits between the Iranian-backed regime in Damascus, and Israel and Britain’s strategic bases on Cyprus just across the sea. Barely 15 miles north of its border is Russia’s naval base at Tartus, the keystone of Putin’s Mediterranean strategy.

Lebanon is staggering under Syrian destabilisation, government corruption, popular anger, Covid and now this devastating explosion. If the West allows it to go under, others will welcome the opportunity for a takeover with baleful consequences for western interests.

Yet, despite troubles which would have destroyed many nations, Lebanon remains a beacon of diversity and tolerance, with its Christian, Sunni, Shiite, Druze and other peoples. How many other countries in the Middle East have two ex-presidents enjoying retirement, in their former fiefdoms? Its universities and its media are arguably the best in the Middle East.

With its bustling and cosmopolitan capital, Beirut, its spirit of entrepreneurship and worldwide links through its highly-networked commercial diaspora all over the globe, the country offers a gateway to the wider Arab world and far beyond. This all represents an opportunity which others are recognising.

China is financing a $60 million Conservatoire near Beirut. President Macron’s high-profile visit, after the explosion, was a surprise to nobody – yet, despite its short period as a French possession, a growing proportion of Lebanese people look towards the Anglophone world for ties. Lebanon was the first Arab country to sign a post-Brexit trade agreement with the UK. More than ever, now is the time to build on our connections.

Liverpool Docks has a stake in the Port of Beirut and the programme to rebuild it will offer opportunities for our construction sector. Two hundred infrastructure projects were planned, before the explosion, utilising $11.6 billion in assistance from international donors; as they come forward, British companies should be bidding for them. On a larger scale, Lebanese ports will be central to the long-delayed programme to rebuild Syria after the destruction in its civil war; infrastructure companies from around the world are waiting for. to this.

Lebanon has a considerable confirmed off-shore oil and gas reserves yet to be exploited, offering yet another opportunity. Tourism and transport offer openings too. The national carrier, Middle East Airlines, placed a large order for Rolls Royce engines last year.

So, the opportunities are there. What is our government’s current role and what else should we be doing?

Since Cameron’s victory in 2010, Britain has recognised the importance of Lebanon and has been providing the kind of high quality, low-cost help which is as valuable as the aid to its refugee camps. Our military mission of just 30 ex-soldiers provide training for the Lebanese Army, one of the few genuinely national institutions drawing from all confessional groups. Ministry of Defence unearthed some pre-packed border strongpoints, designed for Ulster but never used, which have been installed on the Lebanese border and now play a critical role in keeping the horrors of the Syrian Civil War out of Lebanon.

We also set up the Lebanese British Tech Hub which grows small, dynamic tech start-ups to the benefit of both countries. Recently Lord Risby (Richard Spring, the former Foreign Office Minister) has been appointed as our first Lebanese trade envoy and both countries are well served with able ambassadors, Chris Rampling in Beirut, and Rami Mortada in London.

So, when the explosion devastated Beirut, it was appropriate that, in the words of Lebanon’s world famous singer, Shiraz:

“Britain was the first to arrive on the scene of the devastation, and then set a template for other countries to copy.”

With all the goodwill towards Britain, it is time for us to pull together the strands of our assistance to Lebanon and provide additional help in ways which would have a value far beyond any modest cost. This will be made easier by the welcome decision to merge the Foreign Office with the Department for International Development.

I believe that the greatest single requirement in Lebanon is assistance in making the transition to responsible, accountable democracy after a generation of corrupt leadership. The Lebanese Parliament has a finance committee led by the energetic and respected Ibrahim Kanaan. Could we send someone from the National Audit Office to help set up an organisation to assist them?

The Lebanese Central Bank has largely avoided the corruption in government but is struggling with inflation and debt. Could we lend an official to advise them and help with rebuilding the Finance ministry which is in much worse shape? Advice from HMRC on rebuilding the tax base would be valuable too. Lebanon’s Police are not respected in the way their Army is. Seconding a senior British Police officer could do disproportionate good.

Not all initiatives need to be government led. A small group of us have been trying to set up a Lebanese British Business Council, independent of government, hopefully to be resuscitated after Covid.

In summary, the multiple crises in Lebanon represent both a critical threat to Middle Eastern stability and an opportunity for Britain to build on its established programmes to promote our strategic and economic interests. What is needed is not vast sums of money but the kind of joined-up thinking which this government is instilling throughout Whitehall. The Government is undertaking the largest review to its foreign and defence policy since the end of the Cold War, against the backdrop of Brexit. Lebanon should be recognised as a key country in its region and should become a platform for western influence in the Middle East.
