TONY Blair has called for Angela Merkel to block Brexit by doing “everything possible” to keep Britain in the EU.

Arch-remainer Blair urged the German Chancellor to act and said it would be a “mistake of historic proportions if the United Kingdom leaves the European Union.”

Britain has less than a year to go until its divorce with Brussels, with the departure date of March 29 looming on the horizon.

Merkel has previously described our exit from the EU as “deplorable” and Blair said Brexit would be bad news for the Germans.

The former PM told Business Insider: "Even Europe - especially Germany - has a lot to lose.

“It is in all our interests to maintain barrier-free trade across the continent and to hold liberal democracies together in times when authoritarian structures are resurgent."

He added: "Germany should do everything possible to keep the UK in the EU.

“The most important thing is to keep the door open if the British people decide to reverse their decision by voting on the outcome of the negotiations."

Blair, who led a Labour government from 1997-2007, said Berlin should push for a reversal of Brexit by joining forces with France and push for reform in Brussels.

He said: "Germany can also help to promote a British return to the EU by showing that the EU can change itself.”

The Labour grandee’s comments came after India revealed plans to demand easier access for its citizens to migrate to Britain as part of a post-Brexit free trade deal.

The country's high commissioner to the UK Yashvardhan Sinha said India wants the "best deal possible" with Britain.

But he said it's in no hurry to strike a free trade deal.

And warning Britain that a free trade deal would have to involve opening our borders to Indian migrants, Mr Sinha told Politico: "It is very important that if we need to step up our engagement we need to have that easier access, the ease of travel has to be looked into."
