IF a Brexit game-changer is coming on March 21, Theresa May must stop Labour — and Tory Remainers — from throwing in the towel first.

Talk in Brussels is of a last-minute compromise, perhaps enough to get the PM’s deal over the line. They know No Deal will damage them, Ireland especially. They want the agreement to work.

But we must not blink.

If Labour and Tory Remainers, even some in the Cabinet, approve a delay to Article 50 and seize control from the PM on February 27 it only has upsides for the EU. It can then wait for a much softer Brexit, or none.

Tories, on both party wings, should know this: Every alternative to Mrs May’s deal, with appropriate legal adjustment to the Irish backstop, ends in potential catastrophe for their party.

Their poll leads over Labour will vanish if Brexit is substantially delayed. They will go into a full-throttle reverse if a second referendum gets the nod. Likewise a feeble “Norway-Plus” non-Brexit or a permanent, restrictive customs union.

Or indeed if there’s No Deal chaos, for which they will be blamed.

Mrs May, for her country and party, must face down the threats from all those losing their bottle as the clock ticks down to our exit on March 29.

If they want to quit they must get on with it. Otherwise they must stop bellyaching, back the PM and let her tease out the legal changes her deal needs.

“We all need to hold our nerve,” Mrs May said yesterday. For once, she is dead right.

Border bungle

SAJID Javid’s immigration policy threatens to do the reverse of what the public wants.

No one will believe we have “taken back control” of our borders if the Home Secretary relaxes the rules so far that net migration soars.

4 Sajid Javid's migration plans after Brexit could see numbers of workers from non-EU nations double

He doesn’t want an arbitrary limit — we agree there. But lowering thresholds on pay, skills and entry requirements for all migrants, EU and non-EU, is bound to increase totals dramatically.

Mr Javid has surrendered to the insatiable appetite of big business for cheap, low-skilled foreign labour which has helped keep pay at rock-bottom levels.

But Brexit was an overwhelming demand to reclaim powers for Britain, including over immigration.

No one voted for it to hit record levels.

Golden Banks

TO those now of a certain age, Gordon Banks was a superhero.

4 Gordon Banks was from the glittering England generation who did it for the glory

The 1966 World Cup-winning keeper. The genius whose incredible flying leap somehow kept out that Pele header at Mexico ’70 — and whose career-ending eye injury sent millions into mourning.

England’s greatest goalie. Maybe the world’s greatest. But a man unfailingly modest and decent to the end.

Rest in peace, Banksy.
