The UK has announced it is set to join peace talks with the Taliban to bring an end to the 12-year conflict in Afghanistan that has cost more than 400 British lives.

Washington announced earlier this week that negotiations with the Taliban will begin as early as today in the Gulf state of Qatar.

David Cameron gave his backing to the peace plan and revealed that the UK has been ‘fully engaged’ in the process for some time.

A number of Conservative MPs warn the talks could lead to a sell-out that hands southern Afghanistan back to the militants who have killed 444 British servicemen since 2001. It has also emerged that Taliban fighters are likely to be released as a ‘confidence-building measure’ as part of the talks.

It is understood that British intelligence officers have been conducting secret negotiations with the Taliban for the past two years to help pave the way for the talks. Intelligence agents and diplomats are likely to join in if the initial exchanges suggest that a deal can be done.

Under the terms of the arrangement, the Taliban has vowed to break its links with Al-Qaeda terrorists in exchange for a role in running Afghanistan when Western combat troops withdraw at the end of next year.

The announcement was made immediately after NATO handed over control for combat operations to Afghan security forces in every region of the country.

The talks in the Qatari capital, Doha, where the Taliban has opened an office, may also include representatives of the Afghan government of President Hamid Karzai.

While the US will have its first formal meeting with the Taliban in several years, it is expected that will be quickly followed up by a meeting between the Taliban and the High Peace Council – the structure that President Karzai has set up for talks of this nature.

The initial meeting with the Taliban is likely to be an ‘exchange of agendas’ in which both sides lay out what issues they want addressed. Prisoner exchanges will be one topic for discussion.

MI6 officers have been engaged on and off for more than two years in an attempt to get Afghans to talk to each other. The intelligence service believes this will lead to a positive outcome.

Mr Cameron has acknowledged that the talks would be ‘difficult’ for many people to accept, but he said we need to match the security response in Afghanistan with a political process to try and make sure that as many people as possible give up violence and join the political process.

The Prime Minister said that we should be very proud of what our Armed Forces have done because the proportion of terror plots against Britain emanating from Afghanistan has ‘radically reduced’ since 2001.

Conservative MP Bob Stewart, who commanded British Forces in Bosnia, has warned that the Taliban holds the ‘whip hand’ and negotiators need to ‘get the talks right’ or British service people would have ‘died in vain.’

General Khodaidad of Afghanistan, the former counter-narcotics minister, said the country’s armed forces would need to be able to prevent the return of Taliban control in the south, including Helmand province where British troops have been fighting.

Khodaidad says that the Afghan National Army will not be able to control Afghanistan for the long term. Like others he believes that some parts of Afghanistan will fall into the hands of the Taliban.

The military have always been clear that there needs to be a political solution. The irony now is that the country is not just handed back to the Taliban, the very regime which was toppled by the West in 2001.
