Here are some of the big stories we'll be watching this week.

Migration and Brexit will top the agenda at a key EU summit.

Uber appeals against losing its licence in London.

Leftwing Amlo looks set to win Mexico's presidential election.

And results from South Africa's Steinhoff,

the owner of Poundland, will show

if the scandal-hit retailer can bounce back.

First, in Brussels, EU leaders gather on Thursday

for one of the most difficult summits in years, with member

states badly divided over migration

and how to respond to the US under Donald Trump.

The two-day gathering will cover some of the most fraught issues

for the union - how to break the impasse on a common asylum

policy, how to reform the eurozone,

how to salvage the transatlantic alliance,

and how to handle Brexit.

Gideon Rachman has more.

From the British point of view, the thing

they'll be most worried about is Brexit,

because time is running out.

Britain is meant to be out of the EU by March of next year.

And there are all sorts of incredibly important details

which have not been agreed.

The British will be hoping for some advances.

Frankly, I'm skeptical.

However, from the German and French point of view,

there are other more pressing issues.

Migration is number one.

The government of Angela Merkel in Germany

is actually under threat because its coalition partners

want a much tougher migration regime.

Merkel is pleading for time and saying maybe

she can get a pan-European deal at this council.

So that will be really important,

whether she can do that.

And finally, there's the question of eurozone reform.

Merkel and Macron, the French and German leaders,

have just agreed to have a separate budget

for the eurozone, the countries that use

the European single currency.

But the details are yet to be filled in,

and it's not clear whether the other EU

countries will go for that.

But if it happens, it's a huge development.

Uber will face London's transport authority this week

in a much anticipated hearing about its licence

to operate in the capital.

The ride-hailing app was banned by Transport

for London, or TFL, in September over safety concerns.

Aliya Ram has this analysis.

It's a really important case for Uber

because London is Uber's biggest market in Europe.

TFL banned Uber primarily because of concerns

over how it dealt with security incidents

and how it reported violent incidents to the police.

And since the start of the year, Uber's made

a series of changes intended to appease TFL.

So they've invested millions of pounds in call centre staff

so drivers and riders can call if they have a question or a concern.

They've said they'll start reporting violent incidents to the police.

They've also capped the number of hours

that drivers can work before they

have to take a break, which is a response to concerns

about tired drivers on the road.

So I think they will be going into the hearing

this week very confident and hopeful that they'll

get their licence back, although there were

some expectations that the licence issue would

be settled before the hearing.

And that hasn't happened, so we'll have to see.

Mexico looks set for one of the most profound political shifts

in decades when voters go to the polls on July the 1st.

Andrés Manuel López Obrador, a leftist nationalist,

is more than 20 points clear of his rivals and is predicted

to win a landslide with his Morena party,

dealing a major blow to the ruling Institutional

Revolutionary party.

Amlo, as the 64-year-old is widely known,

is vowing to eradicate corruption

and to revive Mexico's poor south.

He has pledged also to pause the energy

reform that opened Mexico's oil sector to private investment.

But his opponents warn about a return

to the failed policies of Mexico's populist governments of the 1970s.

Steinhoff has been one of the more spectacular

high-profile corporate scandals of recent years.

Equity in the South African retail group,

which owns Poundland in the UK, collapsed

after the discovery of accounting irregularities six months ago.

Jonathan Eley says investors will

be watching Steinhoff results very closely this week

Steinhoff, which is a pan-African retail group,

was the biggest flotation of 2015 on Frankfurt's markets

when it floated there.

Since then, its shares have lost 90% of their value.

Its bonds are junk.

Its former major shareholder is suing it.

And its former chief executive is under investigation

for corruption and fraud.

It's been a quite spectacular fall from grace.

It reports interim results this week.

The key focus with results is normally profits.

In this case, it will be the balance sheets.

There are enormous doubts about what

assets exactly this company owns and how much those assets are worth.

The balance sheet hopefully should give creditors

some confidence as to the financial picture of the company.

That's important because Steinhoff

needs to renegotiate its substantial debts.

And that's what the week ahead looks like from the Financial Times in London.

Goodbye.
