GERMAN Chancellor Angela Merkel has been put under more pressure after the leader of her sister party refused to endorse her for another term. Horst Seehofer, the chairman of the CSU party, which shares power in Germany along with Mrs Merkel’s CDU party, said it was “stupid” to discuss another term now, amid growing anger of her rule among the population. He said both parties should wait until closer to next year’s election before deciding who should represent the alliance. Mr Seehofer said: “I think this is a really stupid discussion. That’s all cheese and baloney.”The President of Bavaria added only “Mickey Mouse” and “ordinary sailors” would discuss Mrs Merkel’s future with confidence at the current time, but warned: “No one can remain at the mercy of someone else”. Rumours are growing that Mr Seehofer and the CSU may put forward another name as leader of the two party’s alliance ahead of next year’s election - or even break-away completely. Ms Merkel herself has done little to quell these rumours, saying: “I will comment on that at the appropriate time. I’m sticking to that.”This controversy comes at a time the Chancellor’s approval ratings in Germany continue to drop, with a majority of Germans now opposing Mrs Merkel taking power for another four-year term. According to a poll by Emnid, 50 per cent of people opposed Mrs Merkel serving another term beyond the 2017 election. Just 42 per cent want her to remain. In November, the same poll found only only 45 per cent opposed another term with 45 per cent in favour of her remaining. Ms Merkel's popularity has plummeted due to her controversial open-door migrant policy, which has been attributed by some to a rise in crime. With 300,000 more migrants expected to arrive in Germany during 2016, this anger is expected to grow as next year's election approaches, leaving Mrs Merkel's future as Chancellor in the balance.
