Five things you need to know today

1. Weather

Met Éireann has had to issue a high temperature warning for the first time in three years as temperatures in the high 20s are forecast. Tuesday is expected to be the hottest day of the year to date with temperatures soaring to 28 degrees in parts of the midlands and western areas.

2. Republican convention

Melania Trump, wife of Donald Trump, sought to puncture her husband's divisive reputation in the first headline speech of the party's convention by casting him as a man who would represent all Americans as president.However Mrs Trump's speech was not without its own controversy as it later emerged that parts of the address appeared to have plagiarised Michelle Obama's speech to the Democratic national convention in 2008.

3. Social housing plans

A Government plan to be published today will propose the building of social housing on a scale not seen in decades.The target for social housing units will be increased from the building of 35,000 by 2021 to a target of between 45,000 and 50,000, the figure recently recommended by the Oireachtas committee on housing.

The plan will contain a push towards so-called “mixed tenure” developments in an effort to ensure that the vast majority of State-owned lands are not used for one type of housing. This will prevent estates and developments that are comprised entirely of council homes, as happened in previous decades.

They're not as bad coming out," the spokeswoman said.

5. Ireland can shape debate on terrorism in Europe
