Is it a slip - "wasn't particular interested"?

[Gray]

From the article -- Women's day

Margaret Thatcher, who ironically wasn't particular interested in women's issues.

Shouldn't it be "particularly interested"?

Also, could we use multiple adverbs the way we have used in this sentence?

Does it sound awkward to ears (or eyes) --

"Margaret Thatcher, who ironically wasn't particularly interested..."?

Could we write this way? --

"Margaret Thatcher - who, ironically, wasn't particularly interested..."

"Margaret Thatcher - who, ironically, wasn't particularly interested..."

That's how I would write it. Agreed.
