The collapse of Carillion has come as a shock to the company’s workers and the public who rely on its services. But it seems that Westminster politicians and City bankers were fully aware of the dodgy dealings going on at the construction and outsourcing giant.

To commemorate the anniversary of Rosa Luxemburg's murder in 1919, we republish the following introduction to a 2014 Mexican edition of her important work, Reform or Revolution. The legacy of this martyr for proletarian revolution endures through her ideas.

By kicking off 2018 with a cabinet reshuffle, May had intended to re-establish her authority over the Tory Party and her cabinet. The Prime Minister hoped to send out a signal that her administration had found a new stability. But it was not to be.

Laurent Wauquiez was elected leader of The Republicans (Les Républicains,LR) on 10 December, by a wide margin (74.6 percent) in the first round of voting. The low voter turnout (42 percent of paying members) shows that the stakes were limited: the new shift to the right had already been acknowledged by the party’s rank and file.

The situation in Ukraine four years after the Euromaidan overthrow of the Yanukovitch government could not be worse from the point of view of the masses. Brutal, IMF-inspired cuts in social spending, curtailment of freedom of expression and widespread corruption dominate the scene. So bad is the situation that even Western imperialists have started to openly voice criticism of the Poroshenko regime, which they backed and helped to install.

The last few days have seen the beginning of a new movement of the Tunisian youth, almost seven years to the day after they overthrew the hated regime of Ben Alí in 2011. This time, a proposed budget, imposed by the IMF, has sparked protests around the country. Dozens of activists have been arrested and one protester killed. The “Fech Nastannou?” (what are we waiting for?) movement is a stark demonstration that having overthrown the dictator did not automatically solve the problems of poverty, unemployment and lack of a future that provoked the uprising in 2011.

Following huge protests against counter-reform of the pensions system in Argentina in December, the right-wing Macri government has launched an offensive of repression and criminalisation against left-wing organisations and activists. Two members of the Partido Obrero (Workers’ Party) have been arrested, and several activists from other organisations (including members of parliament) have been indicted. The International Marxist Tendency expresses its solidarity with the comrades, demands the end to all repression and calls on working-class and solidarity activists internationally to show their support.

The Vietnam War - a 17-hour US documentary spread over ten episodes, recently broadcast in Britain in a truncated form on the BBC - may well be the best such film yet produced on this still-controversial subject.

As was expected, Venezuela’s municipal elections on December 10 produced a landslide victory for the ruling United Socialist Party (PSUV). It won 308 out of 335 local councils winning in 23 out 25 state capitals. The opposition, which stood divided and largely boycotted the election, only managed to win two significant local councils, those of San Cristobal, the capital of Táchira and Libertador, the capital of Mérida.

The factional fights in the ANC have left its 54th National conference in deadlock. It confirmed what we have known all along – that the organisation is in terminal crisis. It also revealed that the ANC is divided straight down the middle. In the end the leadership tried to come to some sort of agreement. But the effect of this has only led to paralysis. The process could end up in court with the ANC even weaker as a result.

The Catalan elections on 21 December represent a slap in the face for the strategy of the Spanish government: of introducing direct rule to smash the independence movement. The Spanish ruling party has been reduced to 3 seats in Catalonia and the pro-independence bloc has once again won an overall majority in the Catalan Parliament.

One phone call from Arlene Foster to the British Prime Minister Theresa May was enough to halt a deal between the European Union and British government, already agreed on Monday 4 December. Arlene Foster is the leader of the Democratic Unionist Party (DUP) in Northern Ireland: a right-wing party with its roots in the anti-Catholicism of its former leader Ian Paisley. It is also pro-life, anti-gay and deeply reactionary.

Under the heckling of 10,000 demonstrators on the morning of Monday 18 December, a new right-wing government was sworn in at Vienna, Austria. The coalition of the right-wing, Conservative Party (ÖVP) and the right-wing Freedom party (FPÖ) took two months to agree on a 182-page coalition program, which outlines the policy of the bourgeois block government for the next five years and (so they say) for the coming decade.

Salvador Nasralla, the opposition candidate, travelled to Washington on Monday, 18 December, to meet with representatives of the OAS, the State Department and human rights organisations, to look for a solution to the post-electoral conflict in Honduras. In another clumsy move, the Supreme Electoral Tribunal (TSE), on Sunday afternoon, 17 December, declared right-wing candidate Juan Orlando Hernández (JOH) of the National Party (and current president) as the winner. Clearly this has been a fraudulent election.

The Catalan elections of 21 December take place in exceptional conditions of repression and limitation of democratic rights. The elections have become a battleground to legitimise (or not) a coup by the 1978 regime, in which article 155 of the Spanish constitution was used to dismiss the Catalan government and disband the Catalan parliament. With two days to go, the result of the elections is hard to predict.
