George Osborne visits Paris for two-day talks — EU reform

“All of us face a threat from foreign fighters and from increasing radicalisation within our countries and its right that we look at what help we can provide to one another”, Cameron was quoted saying before his departure for Indonesia.

Prime Minister David Cameron plans to announce the timing of the vote at the Conservative Party’s conference in October, the newspaper said, with polling day penciled in for June 2016.

“The reluctance in Brussels to allow a member state to leave the European project has encouraged government leaders to believe that the reforms they are seeking will be granted”, the report continued.

He will also reiterate the strength of Anglo-French ties, launching a new joint taskforce to boost Europe’s digital economy.

Using this approach Cameron would try to convince British voters Europe will, if there is a vote to retain EU membership, honour reforms and exemptions negotiated by the government even if there is no actual treaty change or other concrete action before the referendum.

Glasgow-based engineering company Weir Group and Aberdeenshire manufacturing firm Ace Winches are among the businesses taking part in the “One Nation” delegation, which will also take in Singapore, Vietnam and Malaysia.

Mr Cameron said he would be making the case for an EU-Asean deal in talks with the group’s secretary general Le Luong Minh.

Mr Cameron, who is embarking on a trade mission with senior business figures to SE Asia next week, said the UK must become the world’s most “open, trade-minded nation” and grab opportunities to trade with “far-flung lands”.

Tory MP Richard Graham has been appointed as a trade envoy specifically for the Asean economic community, which is due to be established by the end of the year, alongside the similar role he plays in Indonesia.

Around 500 people from Indonesia, which has the world’s largest Muslim population, and 200 from Malaysia are believed to have joined the extremists in Iraq and Syria.

Cameron is expected to hold meetings with Indonesian President Joko Widodo and Malaysian Prime Minister Najib Razak.

Mr Cameron is said to be “keen to explore” whether Britain can offer more practical counter-terrorism support to both countries, such as by disrupting foreign fighters, investigating potential terrorist plots and improving aviation security, the BBC reported.

There are also fears about the release of Islamist terrorists locked up in Indonesia following the Bali bombing in 2005.
